Questions

Are my images uploaded anywhere?

No. This compressor runs entirely in your browser using your device. Your images are never sent to us or any server, so it is completely private, even for sensitive photos and documents.

Which formats can I compress?

JPG, PNG and WebP. You can keep the original format, or convert to WebP for the smallest files, or to JPG. WebP usually gives the biggest savings at the same quality.

Will it lower the quality?

You control it. The quality slider trades size for detail. Around 70 to 80% is usually indistinguishable from the original while cutting the file size a lot. Set it higher for near-lossless, lower for the smallest file.

Why did my PNG barely shrink?

PNG is a lossless format, so the quality slider does not apply to it. To shrink a PNG, either reduce its dimensions with the max width option, or convert it to WebP or JPG, which compress far better.

Is there a file size or count limit?

No limits. Compress as many images as you want, as often as you want, with no sign-up. Very large images just take a moment longer since your own device does the work.

Can I resize as well as compress?

Yes. Pick a max width and any image wider than that is scaled down proportionally before compressing, which shrinks the file even more.
