Xcode asset catalog ready
The export creates AppIcon.appiconset with generated PNG files and Contents.json, ready to replace or import into Assets.xcassets.
Apple Icon Tool
macOS App Icon Generator
Build the Xcode-facing icon package: macOS idiom files, Contents.json, an ICNS download, and the rest of the Apple platform icon set in one browser export.
Built for the actual export workflow
Each page focuses on a different search intent, but the generator exports the same complete Apple icon package.
macOS idiom coverage
The macOS slots cover 16, 32, 128, 256, 512, and @2x Retina variants up to 1024 px.
ICNS alongside AppIconSet
The separate ICNS file is generated from the rendered Mac preview sizes, so desktop packaging workflows can use it directly.
Icon sizes and files
The tables below reflect the files generated by the current browser export code.
