PNG to WebP Converter
PNG to WebP Converter is a free online tool that turns PNG images into WebP format directly in your browser. PNG is a lossless raster format that supports transparency, ideal for logos, icons and screenshots. WebP is a modern Google format that delivers smaller files than JPG or PNG with support for transparency. Drop your PNG file, adjust the quality, and download the WebP instantly — your file never leaves your device, with no upload, server or sign-up required.
Your files never leave your device. Conversion runs locally in your browser using the HTML canvas API. No upload, no server, no storage.

Frequently Asked Questions
How do I convert PNG to WebP?
Drop your PNG file onto the converter (or click to browse), set the output quality, then click Convert and download your WebP image. Everything happens in your browser — no upload required.
Is my PNG file uploaded to a server?
No. The conversion runs entirely in your browser using the HTML canvas API. Your PNG file never leaves your device and is never sent to any server. You can verify this by opening Chrome DevTools → Network while converting.
Does the WebP keep transparency?
Yes. WebP supports an alpha channel, so transparent areas in your PNG are preserved in the output.

Yes. You can add up to 5 PNG files and convert them in one batch, then download each WebP individually or all together.
