The product in one sentence
ikonMaker is a sandboxed Mac App Store–ready tool for developers and designers: drop a logo, choose macOS / iOS / both / 1024×1024 / screenshots, export a folder Xcode understands.
Why it exists
Apple expects a precise matrix of icon sizes. Doing that by hand is slow and error-prone.
ikonMaker produces every required slot, writes correct Contents.json,
and validates on-disk pixel dimensions so bad exports fail early — not in App Store Connect.
Capabilities
PNG, JPEG, HEIC, TIFF, PDF. Best results from a square image at least 1024×1024.
Center square crop, or fit with white padding for non-square art.
macOS, iOS, both, 1024×1024, or Mac App Store screenshots — one timestamped folder.
Live 256 pt preview before you write files.
AppIcon.appiconset, MacAppIcon.iconset, .icns, and root {base}-1024.png.
Full iPhone + iPad ladder, App Store marketing 1024, and root {base}-1024.png.
Standalone marketing PNG + single-size iOS/macOS AppIcon sets for modern Xcode catalogs.
1280×800, 1440×900, 1800×1200, 2560×1600, 2880×1800 for App Store Connect.
1024×1024 marketing icon
Every icon export (macOS, iOS, both, 1024) writes {baseName}-1024.png at the export root
for easy App Store Connect upload.
The 1024×1024 platform also produces:
iOS-SingleSize-AppIcon.appiconset— universal iOS single-size Contents.jsonmacOS-SingleSize-AppIcon.appiconset— macOS single-size Contents.json

- Drag
AppIcon.appiconsetinto Assets.xcassets — or use root{base}-1024.pngfor Connect - Assign the set to the app target (and App Clip if needed)
- Archive — Connect validates the 1024×1024 marketing icon
