Why convert JPG to WEBP?

- Faster pages give visitors a better experience and support good Core Web Vitals scores.
- WebP supports transparency and works in all modern browsers.
Good to know before you convert JPG to WEBP
Use WebP for images on your website. For email attachments, print or older software, JPG is still the safer choice. For background, see the WebP documentation from Google.
Tips for the best WEBP results
- Quality 75 to 85 is a good balance for website images.
- Use a higher quality, 90 or more, for logos and sharp graphics.
- 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.
- A large photo feels slow: your own device does the work, so close other tabs or lower the maximum width.
- The result looks too soft: raise the quality slider, because lower values trade sharpness for a smaller file.
