About JPG to ICO

Turn a JPG into an ICO icon containing the standard 16, 32, and 48 pixel sizes that browsers and Windows expect. We downscale and pack each size locally so the result works as a favicon or app icon.

The icon is built entirely in your browser via WebAssembly. Your source photo never leaves your device.
