Batch PNG to WebP Converter for Mac

macOS does not natively export WebP from Preview or Photos. Converting PNGs to WebP on a Mac usually requires Homebrew and cwebp, or a paid app from the Mac App Store. For one-off batch conversions, a browser tool is faster and requires no setup.

This tool converts PNG files to WebP entirely in your browser on macOS. It works in Safari 14+, Chrome, and Firefox. Drop your PNGs, choose your quality setting, and download the WebP output — no Terminal, no Homebrew, no app installation.

Transparency is fully preserved for PNG files with alpha channels — logos, icons, and UI graphics convert to WebP with their transparent backgrounds intact. Use lossless mode for pixel-perfect output or lossy mode at quality 85 for significantly smaller files.
