What is an ICNS file?

Files that contain the .icns file extension usually store icon image files. These icon image files are used by the Mac OS X operating system. This file format supports both 1 and 8 bit alpha channels as well as multiple image stages including folder icons in both the opened and closed states.

Each ICNS file is associated with a corresponding application. The ICNS file acts like a container file and stores the individual icon and resources within the file container. The icons contained within the files can be scaled by the user's operating system to adjust to the proper display size.
