How does compressing an image work?

Drop one image or a whole set onto the grid. Then press the single Compress button. Each file comes back smaller in the same format it went in as, your JPG as a JPG, your PNG as a PNG. A real progress bar tracks the work. When it finishes, you download one file on its own, or your set as a single zip. There is nothing to configure first. You add your pictures and press one button.

Which formats can you compress?

Which formats can you compress?

The compressor handles the four formats that matter on the web: JPG, PNG, WebP, and AVIF. Each file keeps its own format through the whole job. The tool never turns your JPG into a PNG. It only makes your file lighter. If you do need a different format, that is a separate convert step. Here, the format you bring in is the format you get back.

Does compressing lose quality?

Does compressing lose quality?

Compressing re-saves your picture at a chosen quality. Most photos look the same as the original at a much smaller size. Your JPG, WebP, and AVIF give up a little fine detail you are unlikely to notice. Your PNG is re-optimized with no change to how it looks. Your dimensions and your filename stay exactly as they were. Only the weight comes down, and if you also want to change those dimensions, that is what resize is for.

Where do your files go?

Where do your files go?

Your files are sent to be compressed, then removed automatically a short time after the job. That is usually within a couple of hours. A button lets you delete them the instant you have your download. They are never used to train anything, and never handed to a third party. Each result also gives you a link you can share, pointing at the same short-lived copy.

When should you compress an image?

When should you compress an image?

Three reasons come up again and again. Sharing: a lighter photo slips under the size limit on email and messaging apps. Speed: your smaller image makes a web page load faster, which helps readers and ranking. Storage: a folder of listings or holiday photos takes far less room when every file is trimmed. Match the compression to wherever your picture is headed.

Can you compress many images at once?

Can you compress many images at once?

Both work the same way. Drop a single photo and it comes back on its own, smaller and in its original format. Drop a set and the whole batch runs together, with a real progress count rather than a fake bar. It returns as one zip. Up to thirty images go in a single run. So a whole folder of your pictures is one press of Compress, not one tedious file at a time.

How it works

  1. Add your images

    Drop one image or a whole set onto the grid, or pick them from your device. Up to thirty in a single run.

  2. Press Compress

    One button starts the job. There is no quality slider or format picker, the recommended setting is applied for you.

  3. Watch the progress

    A real progress bar tracks each file as it is made smaller, so you always know how far along the job is.

  4. Check the result

    See how much smaller each file became, and confirm it still looks right, before you keep it.

  5. Download the file

    Save the smaller image, or the zip for a set, to your device. Your files are removed automatically a short time later.

Other tools to finish the job

Compressing is one step. Trim the picture to what matters, fit it to an exact size, or change its format for where it is going.

Frequently asked questions

Does compressing an image reduce its quality?

A little, by design, but it is made to be hard to see. JPG, WebP, and AVIF give up a small amount of fine detail to drop the size, and at the recommended setting most photos look the same as the original. A PNG is re-optimized with no change to how it looks at all.

Which image formats can I compress?

You can compress JPG, PNG, WebP, and AVIF, the four main web formats. Each file keeps its own format through the job, so a JPG comes back as a JPG and a PNG as a PNG. The tool never swaps one format for another.

Can I compress several images at once?

Yes. Drop a whole set onto the grid and one press of Compress runs them all together, then hands you a single zip. A single image comes back on its own instead. Up to thirty pictures go in one run, so a folder is one job, not many.

Where do my files go when I compress them?

Not far, and not for long. Your pictures are compressed, then cleared automatically soon after, with a button to remove them at once. Nothing you send is ever used to train a model or passed to anyone else, and each download link stays valid only while that short-lived copy exists.

How much smaller will my image get?

It depends on the photo and its format, but a typical photo drops a lot of weight with no visible change. The result screen shows exactly how much smaller each file became, so you can see the saving before you keep it.

Does compressing change the format of my image?

No. Compressing keeps each file in the format it arrived in, a JPG stays a JPG, a PNG stays a PNG, and the same for WebP and AVIF. If you want a different format, that is a separate convert step, not part of compressing.

Why would I compress an image?

Usually to share or to speed things up. A lighter photo slips under the size limit on email and messaging apps, loads a web page faster, and takes less room in storage. The smaller file does the same job while asking less of every connection.

How do I compress an image online?

You do not need an account, an install, or any settings. Open the page, add your image or images from your device or a drag, and the one button does the rest. Your smaller files arrive ready to save, either singly or bundled, with a count of how much each one shrank.

The details

Notes from the team on craft, formats, and the small decisions behind a good round crop.

How a file gets smaller without looking worse
Compressing leans on a simple fact about pictures: the eye barely notices a lot of the data a photo carries. A camera stores far more color and fine variation than a screen, or a person glancing at the image, will ever pick out. When a file is re-saved at the recommended quality, the parts most likely to be noticed are kept, while the slivers of detail that almost nobody sees are dropped, and that is where the weight goes. For JPG, WebP, and AVIF this trade is adjustable, and the setting used here is chosen to sit right at the point where the saving is large and the change stays invisible to a normal viewer. A PNG works differently: it is packed more tightly with no loss at all, so it comes back smaller yet exactly the same. The result is a file that does the same job at a fraction of the size.
Why keeping the format matters
It is tempting to think the smallest possible file is always the goal, but the format a picture is in usually exists for a reason. A logo saved as a PNG keeps its sharp edges and transparent background, turning it into a JPG would fill that background and blur the edges. A photo saved as a JPG is understood by everything that opens images, switching it to a newer format could trip up an older app or an email client. Because of that, this tool keeps every file in the format it arrived in and only makes it lighter, so nothing about how the picture behaves changes, just its weight. When you genuinely need a different format, converting is its own deliberate step with its own page, where the trade-offs of that change are spelled out, rather than something that happens to you silently while you were only trying to save space.
Why one button beats a wall of settings
Older compressors hand you a quality slider, a format menu, and a before-and-after view, and then leave you to guess. In practice almost everyone wants the same thing: the smallest file that still looks right, and finding that by dragging a slider back and forth is slow and easy to get wrong. This tool removes the guesswork by applying a single recommended quality that has been tuned to land at that sweet spot for typical photos, so one press of Compress gives you the result most people would have arrived at after minutes of fiddling. Fewer choices is not a limitation here, it is the point: you add your pictures, press one button, and get a smaller file you can trust, with the result screen showing exactly how much you saved.
