Why Convert PNG to WebP?
WebP keeps PNG transparency while producing far smaller files, ideal for logos and UI graphics on the web.
This converter redraws your PNG image onto an HTML canvas and re-encodes it as WebP, entirely inside your browser. Nothing is uploaded to a server, so it is fast, private and works even on a slow connection. The output keeps the original pixel dimensions.
