Frequently asked questions

What is an app icon generator?

An app icon generator takes one square master image and exports every pixel size Apple and Google require — iOS AppIcon.appiconset slots, Android mipmap densities, and store listing icons — packaged in a ZIP you can drop into Xcode or Android Studio.

Do I need a 1024×1024 image?

Yes, for best results use a square PNG or JPG at least 1024×1024 px. That is the App Store marketing size and the source we downscale for every smaller icon.

Does this work for Xcode Asset Catalog?

Yes. The iOS export includes every AppIcon.appiconset size for iPhone, iPad, Apple Watch, and Mac. See our dedicated Xcode app icon generator page for a focused workflow.

Are Android adaptive icons supported?

We generate standard and round launcher icons at every mipmap density plus the 512×512 Play Store icon. For Android-only exports, use the Android icon generator landing page.

Can I resize App Store screenshots too?

Yes — use the Screenshot tab above or the App Store screenshot resizer page to batch-export official iPhone, iPad, and Google Play dimensions.

Is App Asset Generator free?

App icons, screenshots, and favicons are free with no sign-up. Some heavier file converters include a daily free limit; see Pricing for credit packs.
