Convert JPG to WebP

WebP is a modern image format that typically produces 25–35% smaller files than JPG at similar visual quality, which is why most site speed audits recommend it. If you're optimizing a website or blog, converting your JPGs to WebP is an easy win.

FAQ

Is WebP supported by all browsers?

Yes — all modern browsers (Chrome, Firefox, Safari, Edge) support WebP for both display and, as here, encoding/decoding.

Why is WebP smaller than JPG?

WebP uses a more efficient compression algorithm than JPG's older codec, so it can hit similar visual quality at a meaningfully smaller file size.

Should I keep a JPG backup?

It's a good idea if you might need to open the image in older software that lacks WebP support — the JPG-to-WebP conversion here doesn't delete your original file.
