Compress image
JPG and WebP images are re-encoded at the level you choose. PNG files cannot be compressed much without changing format, so by default they are saved as WebP, which is usually far smaller; you can choose JPG instead.
Limiting the longest side (for example to 1920 px) often saves more than lowering quality. If a file would get bigger, the original is kept.
Frequently asked questions
Which level should I choose?
Balanced keeps photos looking good at a much smaller size. Use Strong for chat apps or forms with strict limits.
Why did my PNG become WebP?
PNG is lossless, so re-saving it as PNG barely helps. WebP keeps transparency and is much smaller. Choose JPG if you need maximum compatibility.
Are my photos uploaded?
No. Compression happens in your browser.
