Convert PNG to WebP

WebP is supported by all modern browsers, so it’s ideal for speeding up websites. No sign-up, batch and ZIP supported.

When you should not convert to WebP
All modern browsers support WebP, but in some cases PNG or JPG is the better choice: images for e-mail campaigns (some mail clients don’t display WebP), assets for very old systems and software, and cases where the recipient needs the original format. For website images, WebP is the safe default.
