ICO (Windows Icon) is a file format for storing small images used as icons in Windows operating system and as browser favicons. ICO files can contain multiple images at different sizes (16×16, 32×32, 48×48, 256×256) in a single file, allowing Windows and browsers to pick the best size for each context. ICO is required for website favicons (the small icon in browser tabs).
