Start around 80–86%, then compare detail and size. Images with text or fine texture may need a higher setting.

Frequently asked questions
Is my image uploaded?
No. The selected image is decoded and re-encoded inside this browser tab. The file and output are not uploaded to any server.
Does WebP always beat JPG?
No single format wins for every image. Compare the result at the quality you actually need.
Can I resize while converting?
Yes. Enable output dimensions and preserve the aspect ratio or set width and height manually.
