About PNG to WebP
PNG is excellent for preserving transparency and sharp edges, but its lossless compression produces large files. WebP gives you a smaller file at the same visual quality, and it also supports transparency. That combination makes WebP the better choice for almost any image that will be served on a website or inside an app.
This tool converts PNG files to WebP directly in your browser. If your source PNG has a transparent background, the WebP output preserves it. The conversion runs locally using the Canvas API, so your images never leave your device.
At the default 90% quality, the difference from the original PNG is usually invisible while the file size drops significantly. WebP is supported by all current browsers. We do not add watermarks or impose usage limits.
