Convert JPG photos to WebP and typically save 25–35% in file size at the same visual quality. Smaller images mean faster page loads and better Core Web Vitals, which is why WebP is the go-to format for modern websites.

Pick a quality level or set an exact target file size in KB; the conversion runs entirely in your browser with nothing uploaded.

Frequently asked questions

How much smaller is WebP than JPG?

For photographs, WebP is usually 25–35% smaller than a JPG of equivalent visual quality, thanks to its more modern compression.

Is WebP supported everywhere?

Every current browser supports WebP. The stragglers are older desktop software and some upload forms, for those, keep a JPG copy too.

Should I use lossy or lossless WebP?

Lossy WebP (the default here) is right for photos. Lossless WebP suits graphics, logos and screenshots where every pixel must survive exactly, choose "WebP (Lossless)" in the format menu.
