About the ICO format
ICO (Windows Icon)
An ICO file stores one or more images from 16×16 to 256×256 pixels with transparency. The system or browser picks the size that fits - in a tab, on the taskbar or on the desktop.
To create a favicon, take a square PNG and convert it to ICO, choosing the icon size from 16 to 256 pixels.
Best for favicons and Windows application icons.
