What is a PNG (Portable Network Graphics) file?

PNG, standing for Portable Network Graphics, is a widely used raster image format designed for the web. Created by the PNG Development Group as an open-source, non-patented successor to GIF, PNG files are saved with the .png extension. They feature lossless data compression, which ensures that intricate illustrations, high-contrast text, sharp borders, and alpha transparent layers are preserved without any loss of quality.

ICNS is the icon container file format created by Apple for macOS application bundles. Saved with the .icns extension, an ICNS file bundles multiple resolutions and Retina displays (from 16x16 up to 1024x1024 pixels) in a single package, ensuring application icons render with crystal-clear sharpness in macOS Finder and the Dock.

How to open and use an ICNS file?
