About PNG to WebP

Convert PNG images to WebP, Google's modern format that's typically 25–35% smaller at the same visual quality. Transparency is preserved, and you control the quality level to dial in the size you need for fast-loading web pages.

The re-encode runs entirely in your browser with WebAssembly codecs. Your PNG never leaves your device, so even sensitive graphics stay private.
