IconForge Asset Maker is a focused Mac utility for preparing app icons for Xcode asset catalogs.

Drop in a large square image, choose the platforms you support, pick an output folder, and export ready-to-use .appiconset folders. IconForge writes the expected Contents.json files and PNG sizes so you can replace the asset catalog in your project without hand-building every slot.

Built for Apple developers:

• Create iOS and iPadOS universal 1024px icons, including default, dark, and tinted variants
• Create macOS icon sizes from 16px through 1024px
• Create watchOS 1024px icon sets
• Export directly into an existing Assets.xcassets folder or create a new asset catalog
• Drag and drop source images, or choose an image from Finder
• Save your default output folder and platform choices for repeat exports
• Get clear install instructions after every export

IconForge handles the packaging step after your artwork is ready. Your source image stays on your Mac, and the app exports the PNGs and Contents.json files needed for Xcode asset catalogs.

For developers shipping across Apple platforms, IconForge keeps app icon setup practical: one source image in, Xcode-compatible asset folders out.
