FAQ

What image size should I upload?

We recommend a 1024x1024 pixel image. This is the largest size required (for the App Store marketing icon) and allows us to downscale to smaller sizes while maintaining high quality.

Does this generate the Contents.json for Xcode?

Yes. The zip file for Apple platforms includes the correct folder structure and the JSON file needed by Xcode. You can replace your existing AppIcon.appiconset folder with the generated one.

Is my data private?

Yes. All image processing happens locally in your browser using Web technologies. Your source file is never uploaded to our server.
