About this tool

Convert PNG images to WebP format for smaller file sizes and faster websites. This tool runs entirely in your browser — no file upload, no account required, and no data is ever sent to a server. The conversion uses the browser's built-in Canvas API for accurate, lossless pixel manipulation.

  • ✅ Files never leave your device
  • ✅ Instant conversion

How it works

Your file is loaded into an HTML Canvas element at its original dimensions. The Canvas API reads and re-encodes the pixel data in the target format. The result is served as a download directly from your browser — no round-trip to a server.
