How to create an AppIcon.appiconset from a single logo

Turning one logo into a complete iOS icon pack sounds simple, but the details matter. You need consistent spacing, clean scaling, correct PNG output, and a valid Contents.json file so Xcode can understand the export.

Start with the best possible source image

Your source should be square and reasonably large. A 1024x1024 PNG is a strong baseline. If the logo contains very thin lines or tiny text, enlarge the artwork area before export so the smaller icon sizes do not become muddy.

Choose background and padding intentionally

Some icons look stronger with a solid background and comfortable inner padding. Others need a transparent background because the icon shape already carries its own container. The correct choice depends on brand style, but consistency matters more than novelty.

Export the complete asset folder, not just a few PNG files

The real productivity gain comes from exporting a full AppIcon.appiconset package. That means the image files and the matching Contents.json. Without the JSON file, you may still end up manually matching assets in Xcode.

Import into Xcode

Open your project, locate Assets.xcassets, then replace the existing app icon set with the generated files. If your project already has an AppIcon asset set, dropping in the exported content is usually the fastest route.

To skip the repetitive export step, try the homepage generator and download the full asset set in one click.
