Free browser tool
Convert PNG images to smaller WebP files in your browser while keeping transparency when the browser encoder supports it.
Choose one or more PNG files to begin.
Use this tool when you need a smaller image for web delivery and the destination supports WebP. WebP can help reduce file sizes, but transparent images should be previewed after conversion. Very small icons may not always become smaller — the WebP container overhead can cancel any savings. Keep PNG when a workflow requires exact PNG output, legacy tooling, or lossless editing.
