Icns files are used on Mac OS X systems to store icons for applications. The icns files end with a .icns extension. An icns file can store multiple icons within itself. The Apple Icon Image format used for the files supports icons of 16 × 16, 32 × 32, 48 × 48, 128 × 128, 256 × 256, 512 × 512, and 1024 × 1024 pixels in size. OS X can scale the fixed-size icons to be displayed at any intermediate size. You can view the icons stored within a .icns file on an OS X system using the Preview program found in the Applications directory.
