Tips for the best WEBP results
- Quality 75 to 85 is a good balance for website images.

- Check that the software you plan to use supports WebP.
- Resize large photos first for even smaller files.
Common problems and fixes
- WebP will not save: older versions of Safari cannot create WebP files. Use Chrome, Edge or Firefox, or choose JPG.
