Convert PNG to WebP free — typically 25–70% smaller. Browser-based, no upload.

PNG uses lossless compression — it stores every pixel without any quality loss. That's why PNG is the right choice for screenshots, logos, and graphics where every pixel must be exact. The tradeoff is file size: photographic PNGs are large.
WebP uses a more advanced compression algorithm developed by Google. At lossy quality settings (which this tool uses), WebP achieves the same visual quality as PNG at roughly 25–70% of the file size. At quality 85%, a 600KB PNG typically converts to a 150–250KB WebP that looks identical on screen.
WebP also supports full transparency — so if your PNG has a transparent background, that transparency is preserved in the WebP output.
As of 2024, WebP is supported in all modern browsers: Chrome, Firefox, Edge, Opera, and Safari (since version 14, released in 2020). For websites targeting current browsers, WebP is safe to deploy without any fallback. For compatibility with image editors, print workflows, or email clients that may not handle WebP, convert back to PNG or use PNG to JPG instead.
All conversion happens in your browser using the HTML5 Canvas API. Your PNG is never uploaded to any server. After you close the page, nothing persists. For images with sensitive content, this is the safest approach possible.
If you also need to hit a specific file size target after converting, use our image compressor on the resulting WebP.
