Convert PNG to WebP locally in your browser. WebP keeps transparency like PNG but is dramatically smaller — typically 25–70% — making it the ideal format for fast-loading websites and modern app assets. Google created WebP specifically for the web, and it is now supported by every major browser including Chrome, Firefox, Safari, and Edge. Nothing is uploaded to any server.
