Every app icon size from one image

Shipping an app means exporting your icon at a dozen-plus sizes. This generator does it in one step: the full iOS set (40–1024 px, including the App Store marketing icon) and the Android set (mdpi through xxxhdpi mipmaps plus the 512 px Play Store icon), organized into ios/ and android/ folders inside the zip.

Add a background color so transparent logos sit on a solid tile (iOS does not allow transparency in app icons), and use rounded-corner preview to see how the mark reads. Everything renders on your device.

How to generate app icons

  1. Add your icon art — a high-resolution square PNG or an SVG works best.
  2. Pick a background — choose a solid color for iOS, since app icons can't be transparent there.
  3. Switch to App icons — the tool renders the full iOS and Android size set.
  4. Download the zip — drag the ios/ PNGs into Xcode and the android/ mipmaps into your res/ folders.

Tip: no transparency for iOS

iOS app icons must be fully opaque — the system applies its own rounded mask. Set a solid background here so your exported icons are accepted by Xcode and the App Store.

iOS と Android のネイティブアイコンセット: sizes and where each is used

ネイティブアプリを公開するということは、Xcode と Android Studio が想定するフォルダーに整理した十数種類以上のサイズでアイコンを書き出すということです。セットの主要なサイズと、それぞれの使われ方は次のとおりです。

Size File Where it's used
120 × 120 px ios/icon-120.png @3x の iPhone ホーム画面アプリアイコン。ほとんどのユーザーがタップするものです。
152 × 152 / 167 × 167 px ios/icon-152.png · ios/icon-167.png iPad と iPad Pro のホーム画面アプリアイコン。
1024 × 1024 px ios/icon-1024.png Apple が製品ページに表示する App Store のマーケティングアイコン。
48–192 px android/mipmap-mdpi … mipmap-xxxhdpi/ic_launcher.png 各画面密度での Android ランチャーアイコン(mdpi 48 から xxxhdpi 192 まで)。
512 × 512 px android/play-store-512.png Google Play ストアの掲載に必要な高解像度アイコン。

Format & container

高解像度の正方形 PNG または SVG から書き出して、1024 px の App Store アイコンも鮮明に保ちましょう。iOS のアプリアイコンは完全に不透明でなければならず(システムが独自の角丸マスクを適用します)、不透明な背景を設定してください。

How it's wired into your page

                ios/icon-*.png      → Xcode のアセットカタログの AppIcon セットにドラッグ
android/mipmap-*/   → プロジェクトの res/ フォルダーにコピー
android/play-store-512.png → Play Console の掲載情報にアップロード
              

Tip

iOS 向けに角をあらかじめ丸めたり透過を加えたりしないでください。システムが自分でアイコンをマスクするため、Xcode と App Store が受け付けるのは正方形で完全に不透明なタイルです。

よくある質問

Which app icon sizes are included?

iOS: 40, 58, 60, 76, 80, 87, 120, 152, 167, 180, and 1024 px. Android: 48, 72, 96, 144, and 192 px mipmaps plus a 512 px Play Store icon. They're sorted into ios/ and android/ folders in the zip.

Do I need a solid background?

For iOS, yes — app icons can't be transparent. For Android adaptive icons a solid or padded background also helps. Set a color and a little padding before exporting.

Where are the icons generated?

In your browser, on your own device. How any data associated with the tool is handled is described in our privacy policy.

Can I also make a web favicon here?

Yes — switch to Favicon set mode to export favicon.ico, PNG favicons, a manifest, and the HTML for a website instead.
