Convert PNG to WebP

To convert PNG to WebP: upload your PNG and Sevio turns it into WebP, which is typically 25–35% lighter at comparable quality — and for photographs saved as PNG the gain reaches 5–10×. 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.

Frequently asked questions
