Frequently Asked Questions
Q:What icon sizes do I need for iOS and Android apps?
iOS requires a 1024px App Store icon plus device resolutions down to 20px. Google Play requires a 512px store icon plus adaptive mipmap densities (mdpi to xxxhdpi). Web PWAs require 192px and 512px icons. This tool generates all of them simultaneously.
Q:Can I drop the exported zip directly into Xcode?
Yes! The zip contains an AppIcon.appiconset folder with a valid Contents.json file. Simply drag it into Assets.xcassets in Xcode to populate every asset slot instantly.
Q:Does the resizer support Android adaptive icons?
Yes. It creates standard ic_launcher icons, circular ic_launcher_round icons, a 108dp ic_launcher_foreground with a 72dp safe zone, and mipmap-anydpi-v26 XML files.
Q:Why are transparent alpha channels removed from App Store icons?
Both Apple App Store Connect and Google Play Console reject icons containing alpha transparency channels. Our generator automatically flattens transparent backgrounds onto your selected background color.
Q:Is my uploaded icon image sent to a server?
No! All image decoding, resizing, and zip generation happen 100% locally in your web browser using HTML5 Canvas. Your image file never leaves your device.
