About this tool
About this tool
PNG to WebP Converter decodes a PNG and re-encodes it as WebP using the browser canvas. WebP supports an alpha channel, so transparency is preserved, while lossy or lossless encoding typically reduces file size. Everything runs locally in your browser.
PNG graphics with transparency are perfect for logos and UI assets, but they can be heavy. WebP keeps the alpha channel while often cutting file size dramatically. This tool converts your PNG to WebP in the browser with a quality slider and full transparency support.
Built for daily work
- Convert transparent logos and icons for faster-loading websites.
- Optimize UI assets before bundling them into an app.
- Shrink PNG screenshots for blogs and documentation sites.
- Prepare marketing graphics for modern CMS uploads.
