About PNG to ICO

Turn a PNG into an ICO icon containing the standard 16, 32, and 48 pixel sizes — exactly what browsers and Windows expect for a favicon. Transparency is preserved so your icon sits cleanly on any background.

The icon is assembled entirely in your browser via WebAssembly. Your source image never leaves your device.
