JPG, PNG, WebP, HEIC, and more
Converting PNG to WebP can significantly reduce file size while keeping image quality nearly intact. When uploading graphics or logos with transparent backgrounds to the web, PNG files are heavy — but WebP maintains the same transparency while being much lighter, so pages load faster. Conversion happens entirely on your device, and your original PNG stays untouched.
How to use it
- 1Drag and drop the PNG image you want to convert, or click to upload it.
- 2Make sure the output format is set to WebP. (WebP is the default on this page.)
- 3Use the quality slider to balance file size and image quality. Around 80% is usually imperceptible.
- 4Click Convert and you’ll see the file size reduction compared to the original PNG. Hit Download to save — that’s it!
Handy tips
- WebP fully supports transparent backgrounds. You can safely convert graphics that rely on PNG transparency.
- Images with flat colors and shapes (rather than photos) see even more dramatic size reductions in WebP.
- If you need to support very old browsers, keep the original PNG as a backup.

No, your original stays as is. You only download the newly converted WebP, and since everything runs on your device, no files ever leave it.
Most modern browsers and apps support WebP. If you’re worried about very old environments, you can convert back to PNG when needed.
