macOS App Icon Generator
Yes — you can generate a macOS app icon with AI and export every size the .icns format needs. The master macOS icon is 1024×1024 px, and sizes step down to 16×16 px for the smallest views.
Example output
What sizes do you need for a macOS app icon?
macOS packs its icons into an .icns file built from a set of sizes at 1x and 2x (Retina), from a 1024×1024 master down to 16×16. The table below lists the full set Apple expects.
Generate the icon here, then use the free App Icon Generator to export the macOS sizes with correct filenames. Unlike iOS, macOS icons traditionally sit inside a rounded-square canvas with padding — keep the subject centered.
A single, clear subject reads best across the whole range, since the same artwork has to work at 1024 px in the Dock and 16 px in a list.
