iOS / iPadOS Icon Sizes

iOS requires multiple icon sizes for different contexts. All icons must be square PNG files without transparency or rounded corners (iOS applies corners automatically).

Android Icon Sizes

Android uses density-independent folders. Icons are placed inmipmap-*folders for launcher icons.

Tips for Creating Better App Icons

1

Start with 1024×1024

Always design your icon at 1024×1024 pixels. This is the largest size required (iOS App Store) and ensures maximum quality when scaling down.

2

Keep it Simple

App icons are small. Avoid fine details, text, and complex gradients that won't be visible at smaller sizes. Focus on a single, recognizable shape or symbol.

3

Use a Square Canvas

All platforms expect square icons. If your source image isn't square, it will be cropped or padded. Design on a square canvas from the start.

4

Test at Small Sizes

Your icon will appear as small as 16×16 on some platforms. Preview your icon at multiple sizes to ensure it remains recognizable and clear.

5

Avoid Transparency on iOS

iOS does not support transparent app icons. Transparent areas will appear black. Use a solid background for iOS icons.

6

Consider Adaptive Icons for Android

Android 8.0+ uses adaptive icons with separate foreground and background layers. Keep important content within the safe zone (66% center area).

7

Use PNG Format

PNG is the standard format for app icons across all platforms. It supports transparency and lossless compression.

8

No Rounded Corners for iOS

iOS automatically applies rounded corners to your icon. Submit a square icon without rounded corners to avoid double-rounding artifacts.

Integration Guides

Importing into Xcode (iOS / macOS)

  1. Download and unzip your generated icons from AppIconsKit.
  2. Open your Xcode project and navigate to Assets.xcassets.
  3. Delete the existing AppIcon set (if any).
  4. Drag the generated AppIcon.appiconset folder directly into Assets.xcassets.
  5. Build and run your project. Your icons should appear automatically.

Importing into Android Studio

  1. Download and unzip your generated icons from AppIconsKit.
  2. Navigate to your project's app/src/main/res/ directory.
  3. Copy the generated mipmap-* folders into the res/ directory, replacing existing files.
  4. Ensure your AndroidManifest.xml references @mipmap/ic_launcher.
  5. Sync and rebuild your project.
