PNG to WebP converter

Convert PNG images to WebP right in your browser — no upload, no sign-up, completely free. Drop a file (or a whole batch) and download the WebP version in seconds. Your images are processed on your own device and never sent to a server.

PNG is a lossless format that keeps every pixel intact and supports transparency, which makes it ideal for logos, icons, screenshots and graphics with sharp edges or text. WebP is a modern Google format that supports transparency and usually produces files 25–35% smaller than PNG or JPG at a similar quality, which is why it is popular on the web. WebP usually makes noticeably smaller files than PNG, which speeds up websites and saves storage. Transparency is preserved — transparent areas stay transparent in the WebP file.

How to convert PNG to WebP

1. Add your PNG files. Drag your PNG images onto the drop zone, paste, or click to browse. You can add several at once.
2. Convert. Each image is converted to WebP on your device. Use the quality slider to balance size and clarity.
3. Download your WebP files. Save each file, or grab them all together as a ZIP.
