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.
