Frequently asked questions

What quality setting should I use?

70–80% is a good balance for photos — usually a big size reduction with little visible difference.

Why is my PNG bigger after compressing?

PNG is lossless, so the quality slider doesn't apply. Convert to JPG or WebP for much smaller files, especially for photos.
