Compress images to any size.

Select or drop your images, type the size you need in KB or MB, and press Compress. Each image is re-encoded at the highest quality that still fits, then you can download them one by one or as a ZIP.

No. Everything runs in your browser on your own device. Images are only uploaded if you press “Save to Library” — and then they’re stored privately in your account, where only you can see them.

We lower the JPG or WebP quality only as far as needed to hit your size, so most photos look the same. If a size is very small for a large photo, we also reduce the dimensions, because a smaller sharp image looks better than a full-size blurry one.

JPG, PNG, WebP, GIF, BMP and AVIF, plus HEIC on browsers that can open it (like Safari). You can keep the original format or convert to JPG, WebP or PNG while compressing.

Very small targets — for example 10 KB for a large photo — sometimes can’t be reached even after shrinking. In that case we give you the smallest version we could make and mark it, so you can try a larger size or crop the image first.

We use 1 MB = 1024 KB and 1 KB = 1024 bytes, the same as Windows and most upload forms, so a file we make for “200 KB” will pass a 200 KB limit.

Yes. When your images are ready, press “Save to Library”, sign in with your email (it opens in a small window, so your work stays put) and pick a folder. Saved images are private, kept until you delete them, and count towards your 50 GB of storage.

Yes. There’s no sign-up, no watermark and no daily limit — use it as often as you like.
