How png to webp converter works
The browser decodes the PNG and encodes a WebP image. Alpha transparency is preserved; WebP encoding uses the browser’s standard image encoder. Decoded PNG pixels, including transparency, are written as WebP locally.
Important limitations
The browser controls WebP encoding quality. Animated PNG files are converted from the decoded still frame, not as an animation.
Check the result before using it
Try the output in the app, device or workflow that requested it. Review the visible content and format before replacing an original file or sharing a generated link. Browsers and other services can handle edge cases differently, so keep a source copy when the input matters. This tool does not guarantee that a receiving service will accept every result.
Does WebP support transparent images?
Yes. WebP supports transparency, and this converter preserves the decoded alpha channel.
Is input uploaded?
Processing takes place in your browser. This tool does not send your input or selected files to a conversion API.
