Convert PNG to WebP without uploading anything
This tool converts PNG images to WebP entirely in your browser. Each
image is decoded, drawn onto an HTML <canvas>, and re-encoded with the
browser’s canvas.toBlob WebP encoder at the quality you choose.
WebP keeps the PNG alpha channel, so transparency is preserved, while producing a much smaller file. That makes it ideal for logos, icons and graphics you want to serve quickly on the web.
Everything happens locally — your images are never uploaded, stored, or seen by anyone. That makes it both faster and private by design.
