Will quality look worse?

JPEG and WebP are lossy. Start around 75–85% and only go lower if you need a smaller file. We show before/after sizes so you can judge.

No. Compression uses the canvas API in your browser. Images never leave your device.

How it works

Step 3
Download
Save the compressed file, or a zip if you processed several images.

FAQ

PNG is lossless, so a quality slider barely changes size. Choose JPG or WebP as the output format for a much smaller file. Transparency becomes a solid background on JPG.
