Format Details
ICNS
ICNS is Apple's icon format used on macOS and iOS to store application icons at multiple resolutions within a single file. A single ICNS file can contain icons ranging from 16×16 to 1024×1024 pixels, including Retina (2×) variants for high-DPI displays. ICNS files ensure that application icons look sharp at any display size and are required for app distribution in the Apple ecosystem.
ICO
ICO is the Windows icon file format used to display icons for applications, files, folders, and shortcuts in the operating system. It can contain multiple image sizes and color depths within a single file, ensuring icons look sharp at different display scales and DPI settings. ICO files are also used as website favicons — the small icon displayed in browser tabs, bookmarks, and address bars.
