Flickers and flares: Milky Way’s central black hole constantly bubbles with light

James Webb Space Telescope reveals ongoing, rapid-fire light show

The supermassive black hole at the center of the Milky Way appears to be having a party — and it is weird, wild and wonderful.

Using NASA’s James Webb Space Telescope (JWST), a Northwestern University-led team of astrophysicists has gained the longest, most detailed glimpse yet of the void that lurks in middle of our galaxy. 

The swirling disk of gas and dust (or accretion disk) orbiting the central supermassive black hole, called Sagittarius A*, is emitting a constant stream of flares with no periods of rest, the researchers found. While some flares are faint flickers, lasting mere seconds, other flares are blindingly bright eruptions, which spew daily. There also are even fainter flickers that surge for months at a time. The level of activity occurs over a wide range of time — from short interludes to long stretches. 

The new findings could help physicists better understand the fundamental nature of black holes, how they interact with their surrounding environments and the dynamics and evolution of our own galactic home.

The study will be published on Tuesday (Feb. 18) in The Astrophysical Journal Letters.

“Flares are expected to happen in essentially all supermassive black holes, but our black hole is unique,” said Northwestern’s Farhad Yusef-Zadeh, who led the study. “It is always bubbling with activity and never seems to reach a steady state. We observed the black hole multiple times throughout 2023 and 2024, and we noticed changes in every observation. We saw something different each time, which is really remarkable. Nothing ever stayed the same.”

An expert on the Milky Way’s center, Yusef-Zadeh is a professor of physics and astronomy at Northwestern’s Weinberg College of Arts and Sciences. The international team of coauthors includes Howard Bushouse of the Space Telescope Science Institute, Richard G. Arendt of NASA, Mark Wardle of Macquarie University in Australia, Joseph Michail of Harvard & Smithsonian and Claire Chandler of the National Radio Astronomy Observatory.

Random fireworks

To conduct the study, Yusef-Zadeh and his team used the JWST’s near infrared camera (NIRCam), which can simultaneously observe two infrared colors for long stretches of time. With the imaging tool, the researchers observed Sagittarius A* for a total of 48 hours — in 8-to-10-hour increments across one year. This enabled scientists to track how the black hole changed over time.

While Yusef-Zadeh expected to see flares, Sagittarius A* was more active than he anticipated. Simply put: the observations revealed ongoing fireworks of various brightness and durations. The accretion disk surrounding the black hole generated five to six big flares per day and several small sub-flares in between.

“In our data, we saw constantly changing, bubbling brightness,” Yusef-Zadeh said. “And then boom! A big burst of brightness suddenly popped up. Then, it calmed down again. We couldn’t find a pattern in this activity. It appears to be random. The activity profile of the black hole was new and exciting every time that we looked at it.”

Two separate processes at play

Although astrophysicists do not yet fully understand the processes at play, Yusef-Zadeh suspects two separate processes are responsible for the short bursts and longer flares. If the accretion disk is a river, then the short, faint flickers are like small ripples that fluctuate randomly on the river’s surface. The longer, brighter flares, however, are more like tidal waves, caused by more significant events.

Yusef-Zadeh posits that minor disturbances within the accretion disk likely generate the faint flickers. Specifically, turbulent fluctuations within the disk can compress plasma (a hot, electrically charged gas) to cause a temporary burst of radiation. Yusef-Zadeh likens the event to a solar flare.

“It’s similar to how the sun’s magnetic field gathers together, compresses and then erupts a solar flare,” he explained. “Of course, the processes are more dramatic because the environment around a black hole is much more energetic and much more extreme. But the sun’s surface also bubbles with activity.”

Yusef-Zadeh attributes the big, bright flares to magnetic reconnection events — a process where two magnetic fields collide, releasing energy in the form of accelerated particles. Traveling at velocities near the speed of light, these particles emit bright bursts of radiation.

“A magnetic reconnection event is like a spark of static electricity, which, in a sense, also is an ‘electric reconnection,’” Yusef-Zadeh said.

Double vision

Because the JWST’s NIRCam can observe two separate wavelengths (2.1 and 4.8 microns) at the same time, Yusef-Zadeh and his collaborators were able to compare how the flares’ brightness changed with each wavelength. Yusef-Zadeh said capturing light at two wavelengths is like “seeing in color instead of black and white.” By observing Sagittarius A* at multiple wavelengths, he captured a more complete and nuanced picture of its behavior. 

Yet again, the researchers were met with a surprise. Unexpectedly, they discovered events observed at the shorter wavelength changed brightness slightly before the longer-wavelength events.

“This is the first time we have seen a time delay in measurements at these wavelengths,” Yusef-Zadeh said. “We observed these wavelengths simultaneously with NIRCam and noticed the longer wavelength lags behind the shorter one by a very small amount — maybe a few seconds to 40 seconds.”

This time delay provided more clues about the physical processes occurring around the black hole. One explanation is that the particles lose energy over the course of the flare — losing energy quicker at shorter wavelengths than at longer wavelengths. Such changes are expected for particles spiraling around magnetic field lines.

Aiming for an uninterrupted look

To further explore these questions, Yusef-Zadeh hopes to use the JWST to observe Sagittarius A* for a longer period of time. He recently submitted a proposal to observe the black hole for an uninterrupted 24 hours. The longer observation run will help reduce noise, enabling the researchers to see even finer details.

“When you are looking at such weak flaring events, you have to compete with noise,” Yusef-Zadeh said. “If we can observe for 24 hours, then we can reduce the noise to see features that we were unable to see before. That would be amazing. We also can see if these flares show periodicity (or repeat themselves) or if they are truly random.”

The study, “Non-stop variability of Sgr A* using JWST at 2.1 and 4.8 micron wavelengths: Evidence for distinct populations of faint and bright variable emission,” was supported by NASA and the National Science Foundation.

Understanding Neuro Spinal Care in Dubai: Your Path to Healing and Hope

When spine and neurological well-being is concerned, it’s so easy to take things for granted — until something goes awry. Whether it’s chronic back pain, an acute injury, or a neurological condition that impacts your day-to-day life, the urgency for specialized treatment becomes imperative. That’s where neuro spinal care steps in, and Dubai has become one of the top destinations for cutting-edge treatments and patient-focused methodologies.

Let’s get into what Neuro spinal dubai care actually entails, why it is important, and how Dubai is leading the way in world-class treatment.

What is Neuro Spinal Care?

Neuro spinal care is a medical specialty that treats conditions of the brain, spine, and nervous system. This ranges from herniated disks and spinal stenosis to brain tumors, nerve damage, and degenerative spine disease. It brings together neurologists, spine surgeons, physiotherapists, and rehabilitation specialists to create a holistic healing approach.

Really, neuro spinal care isn’t primarily treating pain — really, it’s about gaining back movement, enhancing quality of life, and equipping the patient with tools necessary to again live independently.

Why Dubai Is Becoming A Hub for Neuro Spinal Treatment

Dubai has rapidly emerged as an international healthcare destination, with its world-class medical infrastructure, internationally qualified specialists, and patient-centric approach. For neuro spinal patients, the city boasts a number of advantages:

State-of-the-art Facilities

Dubai hospitals are well-equipped with the latest technology, ranging from high-end MRI and CT scanning equipment to robotic surgical equipment. This ensures that the diagnosis is precise and treatment is as minimally invasive as possible.

Multidisciplinary Teams

Top neuro spinal hospitals in Dubai bring together a team of experts — neurosurgeons, orthopedic spine surgeons, neurologists, pain specialists, and physiotherapists — all under one roof. This allows for a coordinated and personalized treatment plan.

High Standards of Care

Dubai’s healthcare system follows international protocols and standards, offering the kind of care you’d expect in Europe or the US — often with shorter wait times and a more personal touch.

4 Simple Methods to Shrink Your JPEGs

Reducing the size of JPEG images is crucial for anybody looking to increase website loading speed or conserve storage space. Smaller JPEGs use less bandwidth, load more quickly, and are simpler to share. Whether preparing images for your website, emailing them, or just trying to save storage space on your computer, shrinking your JPEG files can be a highly useful skill. In this extensive tutorial, we'll be going through four easy steps on how to reduce your JPEGs and some answers to questions people have when trying to shrink them.

Before you see the real methods for shrinking your JPEG files, though, you first understand how JPEGs function and why you would want to reduce their size.

What is a JPEG and How Does it Work?

In 1992, a compression standard known as JPEG, or Joint Photographic Experts Group, was developed. JPEG is amongst the most prevalent image representation forms on the web and in photography. It's popular because the file size for images can decrease without compromising quality.

JPEG is a lossy compression that discards some of the information from the original image while compressing. Sometimes, this data loss in the given image goes unnoticed by the human eye when the compression is moderate; however, the better you compress a JPEG, the more significant the loss in quality becomes.

JPEG compression is done by discarding less important visual information, such as small color details that the human eye is not very sensitive to. That allows it to compress significantly in file size, while being mostly useful with images having complex color patterns, such as photos. Still, JPEG-compressed images are quite large, so they may sometimes be shrunk further for efficient storage and faster online loading.

Learn how to make your photos look cool in Google Slides.

Why Shrink Your JPEG Images?

Here are a few main reasons for compressing a JPEG image.

Saving Storage Space: Generally, larger sizes of JPEG consume much of your computer's disk space on your phone or even the cloud storage; by shrinking JPEG, you allow more free space for other files to reside.

Faster Website Load Times: For a website owner, large image files can make your web page take longer to load. Smaller JPEGs help enhance page load times, which can be significant for user experience and search engine optimization.

Easier Sharing: Smaller JPEGs are easier to share through email, messaging, or even social networks. It requires less bandwidth and is uploaded much faster.

Faster Backups: The smaller sizes of the file will take much less time to upload to either cloud storage or even to an external hard drive, hence offering faster and quicker backups.

Effortlessly enhance your images using PhotoCut’s AI Image Upscaler.

How to Shrink a JPEG on Windows?

In case you need to shrink a JPEG on your Windows PC, there is an easy way around it. One easy tool is the Photos app. You don't need to download anything else; you can accomplish anything with only one app. This is the process for compressing a JPEG on a Windows PC.

On your PC, find the JPEG picture you want to compress. Double-clicking on it will launch the Photos app by default.

Tap Resize from the drop-down menu that appears after clicking the three dots in the Photos app's top right corner.

You have a range of preset sizes from which you can choose. For example, Small, Medium, or Large; or else, you could go for Define Custom Dimensions so you can put in your preferred pixel dimensions. Be sure to tick the Maintain aspect ratio so the image isn't distorted.

Once you've reduced the size of the image, click Save As and save your new, smaller JPEG file. This file will take up much less storage space but should remain at an acceptable quality level.

Quickly resizing your JPEGs without the need for additional software is possible using the Photos app.

How to Shrink a JPEG on a Mac?

If you're a Mac user, you can utilize Preview to reduce the size of your JPEG file. Here's what you ought to do:

Open Preview and locate the JPEG image you want to shrink. You do this simply by double-clicking on the JPEG image.

Preview View the Tools menu at the top of the page and select Adjust Size. You will see a dialog box where you may adjust the image's pixel size by either entering individual pixel values or changing them by a percentage. It is typically adequate to resize an image to around 50–60% of its original size for Web use.

The file size will automatically appear in the Resolution section of Preview. This will give you an idea of the space you have saved.

Once you've resized it as per your requirement, click OK to let it save the image in the compressed version. You'll then be able to share or upload it easily due to its now decreased size.

Preview is a dependable tool for shrinking JPEGs on your Mac with a simple process and time-saving efficiency.

How to Shrink a JPEG in Photoshop?

Adobe Photoshop is an excellent image editor program, containing the most elaborate tools for the compression and resizing of JPEG images. Below is how you can simply use Photoshop to shrink JPEG by following the following steps:

Open Photoshop and the JPEG image you want to compress.

In the top menu of the screen go to Image Size. In this dialog box, you can now change the Resolution to 72 PPI if you are doing web use. You can now also change the Width and Height dimensions as you need.

Photoshop has many resampling methods that control how the pixels get adjusted when you resize the image. For most high-quality output, Bicubic Sharper is usually your best bet.

Now compress the JPEG a bit by selecting File > Save for Web. Here you will find a Quality slider with which you can get the right balance between the size of your file and image quality. The usual quality for web use would be 60-80%.

Once you have it the way you want it, click on Save to save your compressed JPEG file.

This offers a great deal of control over the compression and resizing process, making Photoshop the best for professional photographers or those who require high-quality adjustments in images.

How to Shrink a JPEG Using an Online Compressor?

For someone who needs to compress an image and doesn't need software for installation, they can use online compressors. Here is one very popular and effective tool, PhotoCut's Online Image Compressor, and how you can compress your JPEG using an online tool:

Go to PhotoCut's online compressor, and upload the JPEG you'd like to shrink.

Using an internet connection, the tool will automatically determine your image's dimensions. Manually enter the width, height, or percentage to resize the image. Just remember that checking Maintain Proportions will avoid any distortion.

This will download the resized image once it compresses the photo. The file will now be smaller, and faster to upload, or share online.

Online compressors are fast and easy to use, having no technical requirements attached to their use. They are perfect for users who have to shrink JPEGs on the go.

Tips for Compressing JPEGs Without Losing Quality

Shrinking JPEGs can easily result in a great loss of quality. Here are a few simple tips on compressing JPEG without sacrificing too much visual integrity.

Choose the Right Compression Level: JPEG also gives you the option to change compression. A higher degree of compression of 80-90% will minimize loss of quality; however, the file will be much larger. A lower degree of compression of 50-60% will provide a much smaller file but with visible artifacts like blurring.

Crop the Image: If an image has too much white space or blank regions, crop it before compressing. This will save on file size and deliver the salient parts of the image.

Choose the Correct Format: PNG for transparent pictures and GIF for animations are options if you don't need every feature of a JPEG. Because lossless compression is used in each of these formats, no quality is compromised during compression.

Keep Backup Files: Always have a backup file of the original high-quality version before compressing images. In this way, you can always revert to the original if the compressed file does not meet your requirements.

Learn everything you need to know about removing filters from photos.

Conclusion

Shrinking JPEG images is a very necessary activity for people seeking to save storage space, enhance websites, or share images more efficiently. Whether using what comes with the Windows or Mac, more advanced software such as Adobe Photoshop, or even online tools, there is more than one way to miniaturize these JPEG files. Knowing the additional techniques and advice this article supports can help you reduce the size of your JPEGs without significantly deteriorating the image quality, making them appropriate for daily usage.

Taming the ZFS Beast: Unlocking Performance and Reliability on Linux

In the sprawling landscape of Linux file systems, ZFS stands as a towering colossus, blending robustness with versatility. Born in the labs of Sun Microsystems, ZFS is no mere storage solution—it’s a philosophy, a promise of data integrity, and a toolkit for the discerning sysadmin. Yet, its power comes with complexity, a labyrinth that can daunt even seasoned professionals. How does one harness this beast without being overwhelmed by its intricacies? This article dives deep into practical strategies for optimizing ZFS on Linux, offering insights to transform its potential into performance. From tuning parameters to sidestepping common pitfalls, the journey promises clarity and control.

Understanding ZFS: The Foundation of Optimization

ZFS is not just a file system; it’s a paradigm shift. Imagine a librarian who not only organizes books but also verifies their contents, duplicates rare manuscripts, and rebuilds damaged pages on the fly. That’s ZFS—combining storage, volume management, and data protection in one seamless package. Its features, like copy-on-write, snapshots, and checksums, ensure data integrity, while its pooling model abstracts physical disks into flexible, scalable storage. But with great power comes great responsibility. Misconfigure ZFS, and you’re not just slowing down your system—you’re tethering a racehorse to a plow.

To optimize ZFS, one must first grasp its core mechanics. Copy-on-write, for instance, ensures that data modifications create new blocks rather than overwriting old ones, preserving snapshots and enabling rollback. This elegance, however, demands ample memory and careful tuning. Similarly, ZFS’s Adaptive Replacement Cache (ARC) acts as a vigilant gatekeeper, caching frequently accessed data in RAM. Yet, without proper sizing, ARC can greedily consume memory, starving other processes. Understanding these dynamics is the bedrock of effective optimization.

Sizing the ARC: Balancing Memory Hunger

Memory is the lifeblood of ZFS performance, and the ARC is its beating heart. Picture a bustling marketplace where the most sought-after goods are kept within arm’s reach—this is ARC, dynamically caching data to minimize disk I/O. But left unchecked, ARC can become a glutton, hoarding RAM at the expense of other applications. How, then, does one strike a balance?

The key lies in tuning the zfs_arc_max parameter. By default, ZFS allows ARC to consume up to half of the system’s RAM, but this can be excessive on memory-constrained systems. For a server with 32GB of RAM, setting zfs_arc_max to 8GB or 12GB often yields better results, leaving headroom for other processes. This adjustment is made by editing /sys/module/zfs/parameters/zfs_arc_max or adding a line to /etc/modprobe.d/zfs.conf. For example, to cap ARC at 8GB, one might set options zfs zfs_arc_max=8589934592 (8GB in bytes).

Consider a real-world scenario: a small business running a file server on a Linux box with 16GB of RAM. Without tuning, ZFS’s ARC might claim 8GB, leaving the system sluggish during peak usage. By capping ARC at 4GB, the server breathes easier, serving files swiftly while multitasking. It’s a delicate dance—too little ARC, and performance suffers; too much, and the system chokes. Experimentation, guided by tools like arcstat, reveals the sweet spot.

Compression: Squeezing More from Your Disks

In the quest for efficiency, ZFS’s compression feature is a hidden gem, a magician pulling extra space from thin air. Unlike traditional file compression, ZFS compresses data on-the-fly, transparently, before writing it to disk. The result? Smaller footprints, faster I/O, and, in some cases, better performance. But is compression always a win, or does it come with strings attached?

The lz4 compression algorithm, ZFS’s default, is a lightweight champion, offering a near-perfect balance of speed and compression ratio. For datasets like text files, logs, or virtual machine images, lz4 can shrink data by 20-50%, reducing disk writes and amplifying throughput. On a busy database server, enabling lz4 compression might halve storage demands while speeding up queries, as less data travels between disk and memory. https://fileenergy.com/ To enable it, simply run zfs set compression=lz4 poolname/dataset.

Yet, compression isn’t a universal cure. For already-compressed data—like videos or encrypted files—lz4 yields negligible savings while burning CPU cycles. A media server storing HD movies, for instance, might skip compression entirely, preserving processing power for streaming. The heuristic is simple: if the data is compressible, enable lz4; if not, leave it off. Tools like zfs get compressratio help monitor effectiveness, ensuring you’re not chasing diminishing returns.

ZIL and SLOG: Taming Synchronous Writes

Synchronous writes are the Achilles’ heel of many file systems, and ZFS is no exception. Applications like databases or mail servers demand that data be committed to stable storage before proceeding, introducing latency. ZFS’s ZIL (ZFS Intent Log) handles these writes, acting as a temporary staging area. But on spinning disks, the ZIL can become a bottleneck, grinding performance to a halt. How does one escape this quagmire?

Enter the SLOG (Separate Log device), a dedicated, high-speed device—typically an SSD—used to offload ZIL writes. Think of it as a sprinter carrying urgent messages, bypassing the plodding pace of mechanical disks. Adding an SLOG to a ZFS pool can slash latency for synchronous workloads. For example, a PostgreSQL server running on a ZFS pool with an SLOG might see transaction times drop from milliseconds to microseconds, a boon for high-throughput applications.

Configuring an SLOG requires care. The device should be fast, with low latency and high endurance, as it handles frequent, small writes. Consumer SSDs may wear out quickly, so enterprise-grade NVMe drives or Optane devices are preferred. To add an SLOG, use zpool add poolname log /dev/nvme0n1. But beware: an SLOG doesn’t accelerate asynchronous writes, so it’s not a cure-all. For workloads with minimal synchronous writes, the cost of an SLOG may outweigh its benefits. A small e-commerce server, for instance, might skip the SLOG, relying on a well-tuned ZIL instead.

Snapshots: Balancing Protection and Performance

ZFS snapshots are a sysadmin’s safety net, capturing point-in-time copies of data with minimal overhead. They’re the time machine of file systems, enabling rollbacks after accidental deletions or ransomware attacks. But snapshots, like any powerful tool, demand judicious use. Overzealous snapshotting can bloat storage and slow performance, turning a lifesaver into a liability.

The trick is to tailor snapshot policies to your needs. A busy web server might take hourly snapshots, retained for a day, with daily snapshots kept for a week. This balances protection with storage efficiency. Tools like zfs-auto-snapshot automate this process, but manual tuning is often wiser. For instance, setting zfs set com.sun:auto-snapshot=true poolname/dataset enables automatic snapshots, but you’ll want to adjust retention periods to avoid clutter.

Consider a university’s file server, hosting student projects. Frequent snapshots protect against accidental overwrites, but retaining them indefinitely consumes terabytes. By limiting snapshots to a week, the server stays lean, freeing space for new projects. Conversely, a financial institution might retain snapshots for months, prioritizing compliance over storage. The mantra is clear: snapshot with purpose, not paranoia.

RAID-Z and Disk Topology: Building a Resilient Foundation

ZFS’s RAID-Z levels (RAID-Z1, Z2, Z3) offer redundancy akin to traditional RAID, but with a twist: they integrate seamlessly with ZFS’s checksums and self-healing. Choosing the right topology is like laying a house’s foundation—get it wrong, and the whole structure wobbles. RAID-Z1 tolerates one disk failure, Z2 two, and Z3 three, but each level trades performance for resilience.

For a home NAS, RAID-Z1 with four disks might suffice, balancing cost and redundancy. But a corporate backup server, guarding critical data, demands RAID-Z2 or Z3, even if it means slower writes. Disk count matters too—wider vdevs (virtual devices) increase I/O but amplify rebuild times. A 12-disk RAID-Z2 vdev might scream with throughput but crawl during resilvering, testing patience. The sweet spot often lies in 6-8 disks per vdev, a compromise between speed and manageability.

Disk alignment also plays a role. Modern 4Kn drives require proper ashift settings (ashift=12) to avoid performance penalties. Misaligned pools, like a car with unbalanced tires, wobble under load. Creating a pool with zpool create -o ashift=12 poolname raidz2 /dev/sda /dev/sdb ... ensures harmony. A media company learned this the hard way: their misaligned RAID-Z1 pool choked on video renders until a rebuild with correct ashift restored fluidity.

Monitoring and Maintenance: Keeping ZFS Healthy

A ZFS pool is a living entity, demanding regular care to stay vibrant. Neglect it, and silent errors creep in, eroding reliability. Monitoring tools like zpool status and zfs list are your stethoscope, revealing the pool’s pulse. Scrubbing, ZFS’s self-healing process, checks data integrity, repairing errors before they fester. Scheduling monthly scrubs, via zpool scrub poolname, keeps corruption at bay.

Performance monitoring is equally vital. Tools like iostat and zpool iostat expose bottlenecks, while arc_summary dissects ARC behavior. A cloud provider once traced sluggish VM performance to an overtaxed ARC, resolved by tweaking zfs_arc_max. Alerts, configured via zfs event or third-party tools like Zabbix, catch issues early, preventing outages.

Maintenance extends to upgrades. ZFS on Linux, maintained by the OpenZFS project, evolves rapidly. Upgrading to the latest version—say, OpenZFS 2.2—unlocks features like faster compression or improved RAID-Z performance. But test upgrades in a sandbox; a hasty update once crippled a research lab’s pool, costing days of recovery. Patience here is a virtue.

The Road Ahead: Mastering ZFS

ZFS on Linux is a journey, not a destination. Its complexity, like a dense forest, can overwhelm, but with the right tools and knowledge, it becomes a playground of possibilities. From tuning ARC to leveraging compression, each optimization is a step toward mastery. The sysadmin who tames ZFS doesn’t just manage storage—they wield a scalpel, carving efficiency from chaos.

Yet, the path demands vigilance. Every system is unique, and what works for a NAS may falter on a database server. Experiment, monitor, and adapt. As the philosopher Heraclitus might have said, no one steps into the same ZFS pool twice—it evolves, as must you. So dive in, tweak those parameters, and let ZFS’s power propel your Linux system to new heights.

4 Simple Methods to Shrink Your JPEGs

Reducing the size of JPEG images is crucial for anybody looking to increase website loading speed or conserve storage space. Smaller JPEGs use less bandwidth, load more quickly, and are simpler to share. Whether preparing images for your website, emailing them, or just trying to save storage space on your computer, shrinking your JPEG files can be a highly useful skill. In this extensive tutorial, we'll be going through four easy steps on how to reduce your JPEGs and some answers to questions people have when trying to shrink them.

Before you see the real methods for shrinking your JPEG files, though, you first understand how JPEGs function and why you would want to reduce their size.

What is a JPEG and How Does it Work?

In 1992, a compression standard known as JPEG, or Joint Photographic Experts Group, was developed. JPEG is amongst the most prevalent image representation forms on the web and in photography. It's popular because the file size for images can decrease without compromising quality.

JPEG is a lossy compression that discards some of the information from the original image while compressing. Sometimes, this data loss in the given image goes unnoticed by the human eye when the compression is moderate; however, the better you compress a JPEG, the more significant the loss in quality becomes.

JPEG compression is done by discarding less important visual information, such as small color details that the human eye is not very sensitive to. That allows it to compress significantly in file size, while being mostly useful with images having complex color patterns, such as photos. Still, JPEG-compressed images are quite large, so they may sometimes be shrunk further for efficient storage and faster online loading.

Learn how to make your photos look cool in Google Slides.

Why Shrink Your JPEG Images?

Here are a few main reasons for compressing a JPEG image.

Saving Storage Space: Generally, larger sizes of JPEG consume much of your computer's disk space on your phone or even the cloud storage; by shrinking JPEG, you allow more free space for other files to reside.

Faster Website Load Times: For a website owner, large image files can make your web page take longer to load. Smaller JPEGs help enhance page load times, which can be significant for user experience and search engine optimization.

Easier Sharing: Smaller JPEGs are easier to share through email, messaging, or even social networks. It requires less bandwidth and is uploaded much faster.

Faster Backups: The smaller sizes of the file will take much less time to upload to either cloud storage or even to an external hard drive, hence offering faster and quicker backups.

Effortlessly enhance your images using PhotoCut’s AI Image Upscaler.

How to Shrink a JPEG on Windows?

In case you need to shrink a JPEG on your Windows PC, there is an easy way around it. One easy tool is the Photos app. You don't need to download anything else; you can accomplish anything with only one app. This is the process for compressing a JPEG on a Windows PC.

On your PC, find the JPEG picture you want to compress. Double-clicking on it will launch the Photos app by default.

Tap Resize from the drop-down menu that appears after clicking the three dots in the Photos app's top right corner.

You have a range of preset sizes from which you can choose. For example, Small, Medium, or Large; or else, you could go for Define Custom Dimensions so you can put in your preferred pixel dimensions. Be sure to tick the Maintain aspect ratio so the image isn't distorted.

Once you've reduced the size of the image, click Save As and save your new, smaller JPEG file. This file will take up much less storage space but should remain at an acceptable quality level.

Quickly resizing your JPEGs without the need for additional software is possible using the Photos app.

How to Shrink a JPEG on a Mac?

If you're a Mac user, you can utilize Preview to reduce the size of your JPEG file. Here's what you ought to do:

Open Preview and locate the JPEG image you want to shrink. You do this simply by double-clicking on the JPEG image.

Preview View the Tools menu at the top of the page and select Adjust Size. You will see a dialog box where you may adjust the image's pixel size by either entering individual pixel values or changing them by a percentage. It is typically adequate to resize an image to around 50–60% of its original size for Web use.

The file size will automatically appear in the Resolution section of Preview. This will give you an idea of the space you have saved.

Once you've resized it as per your requirement, click OK to let it save the image in the compressed version. You'll then be able to share or upload it easily due to its now decreased size.

Preview is a dependable tool for shrinking JPEGs on your Mac with a simple process and time-saving efficiency.

How to Shrink a JPEG in Photoshop?

Adobe Photoshop is an excellent image editor program, containing the most elaborate tools for the compression and resizing of JPEG images. Below is how you can simply use Photoshop to shrink JPEG by following the following steps:

Open Photoshop and the JPEG image you want to compress.

In the top menu of the screen go to Image Size. In this dialog box, you can now change the Resolution to 72 PPI if you are doing web use. You can now also change the Width and Height dimensions as you need.

Photoshop has many resampling methods that control how the pixels get adjusted when you resize the image. For most high-quality output, Bicubic Sharper is usually your best bet.

Now compress the JPEG a bit by selecting File > Save for Web. Here you will find a Quality slider with which you can get the right balance between the size of your file and image quality. The usual quality for web use would be 60-80%.

Once you have it the way you want it, click on Save to save your compressed JPEG file.

This offers a great deal of control over the compression and resizing process, making Photoshop the best for professional photographers or those who require high-quality adjustments in images.

How to Shrink a JPEG Using an Online Compressor?

For someone who needs to compress an image and doesn't need software for installation, they can use online compressors. Here is one very popular and effective tool, PhotoCut's Online Image Compressor, and how you can compress your JPEG using an online tool:

Go to PhotoCut's online compressor, and upload the JPEG you'd like to shrink.

Using an internet connection, the tool will automatically determine your image's dimensions. Manually enter the width, height, or percentage to resize the image. Just remember that checking Maintain Proportions will avoid any distortion.

This will download the resized image once it compresses the photo. The file will now be smaller, and faster to upload, or share online.

Online compressors are fast and easy to use, having no technical requirements attached to their use. They are perfect for users who have to shrink JPEGs on the go.

Tips for Compressing JPEGs Without Losing Quality

Shrinking JPEGs can easily result in a great loss of quality. Here are a few simple tips on compressing JPEG without sacrificing too much visual integrity.

Choose the Right Compression Level: JPEG also gives you the option to change compression. A higher degree of compression of 80-90% will minimize loss of quality; however, the file will be much larger. A lower degree of compression of 50-60% will provide a much smaller file but with visible artifacts like blurring.

Crop the Image: If an image has too much white space or blank regions, crop it before compressing. This will save on file size and deliver the salient parts of the image.

Choose the Correct Format: PNG for transparent pictures and GIF for animations are options if you don't need every feature of a JPEG. Because lossless compression is used in each of these formats, no quality is compromised during compression.

Keep Backup Files: Always have a backup file of the original high-quality version before compressing images. In this way, you can always revert to the original if the compressed file does not meet your requirements.

Learn everything you need to know about removing filters from photos.

Conclusion

Shrinking JPEG images is a very necessary activity for people seeking to save storage space, enhance websites, or share images more efficiently. Whether using what comes with the Windows or Mac, more advanced software such as Adobe Photoshop, or even online tools, there is more than one way to miniaturize these JPEG files.
