Convert PNG to WebP without uploading your file

WebP gives you most of PNG’s quality at a fraction of the file size, with transparency support intact. Convert in your browser.

The conversion runs entirely in your browser. The file never leaves your computer. No signup, no upload, no tracking.

WebP supports transparency the same way PNG does, so screenshots and logos with alpha channels keep their transparency. Expect file sizes about 25 to 35 percent smaller than the original PNG.

When to convert PNG to WebP

WebP is the best choice when you need smaller files for the web without losing transparency. Unlike JPEG, WebP preserves alpha channels the same way PNG does, but at a fraction of the file size. Every modern browser (Chrome, Firefox, Safari, Edge) supports WebP. The only reason to stick with PNG is when the destination software or device does not support WebP yet, which is increasingly rare.
