How to use PNG to WebP.
Select a PNG
Choose a PNG image or try the sample. The file stays in your browser.
Choose quality
Adjust WebP quality and optionally cap the longest edge. Original dimensions are selected by default.
Preview and download
Convert the image, check transparent areas and small text, then download the WebP. Compare file sizes; conversion is not always a size win.
Transparency stays in the output.
The converter does not paint a background under the PNG. Transparent pixels remain transparent in the WebP file, which is useful for interface cutouts and overlays.
Check browser and CMS support at the destination.
Modern browsers display WebP, but an email client, document editor, or older publishing system may prefer PNG or JPEG. Keep the PNG as your source and test the final placement.
