JPG to WebP, in your browser
If you’re publishing images to the web, WebP is almost always the better format: it’s typically 25–35% smaller than JPG at the same quality, so pages load faster and use less bandwidth — with no visible loss. Converting your JPGs to WebP is one of the simplest performance wins for a website, store or blog.
Mynify converts on your device using the browser’s native WebP encoder — nothing is uploaded.
Why it’s worth doing
- Faster pages. Smaller images mean quicker loads and better Core Web Vitals.
- Lower bandwidth. Useful at scale, and for mobile visitors.
- Same quality. At matching quality settings, viewers won’t see a difference.
The one caveat: a handful of older desktop apps and email clients still don’t read WebP. For anything web-facing, WebP is the right call; for legacy software, stick with JPG.
Tip
Converting a whole folder of a site’s JPGs to WebP can cut total page weight dramatically. Pair with resize if the images are larger than they display.
