What is ICNS?
ICNS (Apple Icon Image) is the format macOS uses for application icons. A single .icns file bundles many resolutions, from small menu-bar sizes up to high-resolution Retina versions, so the system can display a crisp icon at any size. Developers ship it inside the resources of a Mac app bundle.
ICNS supports both lossy and lossless compression, so file size and fidelity depend on how each file was encoded. It supports transparency.
ICNS was developed by Apple.
