ICNS - Apple Icon Image

 

Format introduction:

The Apple Icon Image format is an icon format used in Apple Inc.'s macOS. It supports icons of 16 x 16, 32 x 32, 48 x 48, 128 x 128, 256 x 256, 512 x 512 points at 1x and 2x scale, with both 1- and 8-bit alpha channels and multiple image states (example: open and closed folders). The fixed-size icons can be scaled by the operating system and displayed at any intermediate size.

Technical details:

The file format consists of an 8 byte header, followed by any number of icons. Over time the format has been improved and there is support for compression of some parts of the pixel data.
