PNG to WebP
Shrink PNG files into WebP while keeping transparency.
Loading tool…
PNG is the usual choice when you need a transparent background, but the files are large. WebP gives you the best of both: it supports transparency just like PNG, yet produces a much smaller file. That makes it ideal for logos, icons and graphics on a website where load speed matters. This converter changes your PNG to WebP in your browser, so nothing is uploaded and the transparent areas stay transparent.
PNG is where WebP saves the most
Converting a JPG to WebP typically saves a quarter to a third. Converting a PNG usually saves far more, often half the file or better. The reason is that PNG is lossless and stores every pixel exactly, which makes it large by design, while WebP offers a lossless mode that simply compresses the same data far more efficiently. You keep every pixel and lose most of the weight.
Transparency comes along
The usual reason to accept PNG's size is transparency, since JPG cannot do it. WebP can, which removes the trade-off entirely. Logos, icons, cut-out product shots and anything with a transparent background can move to WebP and keep working exactly as before at a fraction of the size. For a site heavy on graphics rather than photographs, this is often the single biggest performance change available.
When to keep the PNG
- Files someone will download and open in older desktop software.
- Assets going into print workflows, which frequently do not accept WebP.
- Anything an upload form specifically asks for as PNG.
- For everything you publish on the web, WebP is the better default.
