Frequently asked questions
What quality should I choose?+
For web uploads, 60–80% works well. At the same quality, WebP is smaller than JPG.

JPG has no transparency and fills it with white. Choose WebP if you need transparency.
Are my files uploaded?+
No. Compression happens in your browser, so images never leave your device.
