About ICO Format

Icon File (.ico)

ICO (Icon) is a file format used for icons in Microsoft Windows. ICO files can contain multiple sizes and color depths in a single file, typically including 16×16, 32×32, 48×48, and 256×256 pixel variants. The 256×256 size uses PNG compression. ICO is also used for website favicons (favicon.ico) displayed in browser tabs. Converting PNG to ICO is a common task for web developers and software creators.
