What image should I use for an ICO favicon?
Start with a square PNG, ideally 512 x 512 or larger. The tool creates multiple favicon sizes inside one ICO file for browser compatibility.

By default this converter includes 16, 32, 48, 64, 128, and 256 pixel PNG frames inside the ICO container. These sizes cover common desktop and browser favicon usage.
