Compress Images

Same look, lighter files. Batch compress in one go.

🔒 Files never leave your device

What this tool does

This tool reduces file size by adjusting save quality — and optionally the maximum width — while keeping your photos looking the same. Use it for upload limits on blogs and shops, email attachments, or faster web pages.

Drop many images at once; they're compressed one after another and saved as JPG or WEBP. Each row shows the original size, the new size and the percentage saved, so you can check the result before downloading.

Pick files with the button, drag them in, or copy a screenshot and paste it with Ctrl+V. If you change the quality or format, images already in the list are recompressed with the new settings — so you can try a few values and keep the one you like.

When it comes in handy

Online stores and marketplaces often cap each image at a few megabytes. Phone photos are frequently several MB each, so lowering the max width and nudging the quality down usually gets them under the limit.

Lots of images can slow a blog or website down. Photos are often uploaded far larger than they're ever displayed; scaling them to around 1280–1920px wide looks much the same on screen while cutting what visitors have to load.

When emailing or messaging a batch of photos, compressing them first helps you stay under attachment limits. Click 'Download all' and you get a single ZIP that's easy to attach.

It's also a quick way to turn bulky PNG screenshots or graphics into lighter WEBP files for storage.

Choosing quality, format and max width

Quality runs from 10 to 100, with 70 as the default. Lower numbers give smaller files, but smooth areas like skies and skin start to show blotches or banding. If quality really matters, try 80–90; if the size limit is tight, start at 50–60.

There are two formats: JPG and WEBP. JPG opens practically everywhere, which makes it the safe choice. WEBP keeps transparency and often comes out smaller at the same quality setting — but some upload forms don't accept it, so stick with JPG if you're unsure.

Max width can be Keep original, 2560px, 1920px, 1280px or 800px. Images are only scaled down when they're wider than the value you pick; narrower images are never enlarged. Height follows the aspect ratio, so nothing gets squashed.

How it compares to other options

You can re-save a photo in a built-in app like Windows Paint to change its size, but that usually means opening and saving each file one by one. Here the same quality, format and width are applied to every image at once, and you see how much each one shrank.

Messaging apps sometimes shrink photos on their own when you send them, but you don't get much say in how much. Compressing here first means you choose the quality and width, so the result is predictable.

If you need to hit an exact size such as 'under 200KB', 'Resize Image to KB' is easier — you type the target and it finds the settings for you.

Things to keep in mind

Every time a JPG is recompressed it loses a little more quality. When you want to try different settings, start from the original photo rather than an already compressed copy.

Max width only looks at the width, so tall portrait photos can still be quite tall. For example, at 1920px a 3024×4032 portrait photo becomes 1920×2560.

Formats your browser can't open — such as iPhone HEIC photos in Chrome — may show 'Failed'. Convert them first with 'HEIC to JPG'.

How to use

Pick quality and output format (the defaults work great).
Drop your photos — they're compressed instantly, many at once.
Download one by one or use 'Download all'.

FAQ

How much smaller will my images get?

Usually 50–80% smaller, depending on the photo. Lower quality means smaller files.

Does it work with PNG?

Yes. Saving PNGs as WEBP or JPG shrinks them a lot. Choose WEBP to keep transparency.

Are my images uploaded?

No. Compression happens in your browser and nothing is sent anywhere.

What if the result is bigger than the original?

If the format and size are unchanged and the result is larger, the original is returned as is. Try a lower quality or a smaller max width.

What happens to the date and location info?

Compressed images don't include photo metadata (EXIF) such as capture date, camera details or GPS location. That's handy when you'd rather not share where a photo was taken, but keep your originals if you sort photos by date. If the original was smaller and returned unchanged, its metadata is still there.

Can I compress animated GIFs?

No. Only the first frame of a GIF is saved, as a still JPG or WEBP. Keep the original GIF if you need the animation.

How do I remove an image from the list?

Click the ✕ on its row — it's removed and won't be included in 'Download all'. To empty the whole list, click 'Clear all' below it.

Tips

Quality between 60 and 80 is usually indistinguishable to the eye (the default is 70).
For phone photos, setting max width to 1920px or 1280px shrinks files far more.
JPG turns transparent areas white. Choose WEBP to keep transparency.
