An ICO file holds the same icon in several sizes, so it looks sharp in the taskbar, in folders and in browser tabs. Add an image, choose how it fits into the square and which sizes to include (16, 24, 32, 48, 64, 128, 256 px), and download a single ICO file. Every size is scaled with a high-quality filter.
