How it works

  2. WebP is already selected as the output format.
  3. Adjust quality if you want a different size/quality balance.
  4. Download the converted WebP file.

Supported formats & limitations

  • PNG (source)
    Lossless with full transparency support.
  • WebP (output)
    Supports transparency with much stronger compression than PNG.
  • Very old browsers (pre-2020 Safari, Internet Explorer) may not display WebP images.
  • Quality below 100% is lossy — compare the result before relying on pixel-perfect output.

Frequently asked questions

Does converting to WebP keep transparency?

Yes. WebP supports transparency the same way PNG does, so transparent areas stay transparent.

Will the WebP file always be smaller than the PNG?

Usually, often significantly — but this depends on the image content. Photos and complex graphics benefit the most.

Do all browsers support WebP?

All current major browsers do. If you need to support very old browsers, keep a PNG version too.
