Batch PNG to WebP Converter for Windows

Converting PNG files to WebP on Windows traditionally requires dedicated software: ImageMagick (command-line), Paint.NET plugins, or a Photoshop subscription. For occasional batch conversions, installing and learning a new tool just to convert a folder of PNGs is overkill.

This browser-based converter works in Chrome, Edge, and Firefox on Windows 10 and 11 with no installation required. Drop your PNG files into the browser, choose lossy or lossless mode, and download the WebP files — individually or as a ZIP. The entire conversion happens in your browser tab; nothing is uploaded.

For web developers on Windows, this tool is ideal for converting assets before deployment. Drop in your design exports, batch convert, and download the WebP versions ready for your CSS and HTML.
