- Choose a background color for any empty area and pick iOS, Android or both.
- Press Download icon set (ZIP).
Frequently asked questions
Which sizes are included?
iOS: the iPhone and iPad sizes from 20 to 180 pixels, plus the 1024 pixel App Store icon. Android: 48, 72, 96, 144 and 192 pixels for mdpi to xxxhdpi, plus 512 pixels for Google Play.
How do I add the icons to Xcode?
Open the ZIP and drag the AppIcon.appiconset folder into your Assets.xcassets, replacing the existing one.
How do I add the icons to Android Studio?
Copy the mipmap folders from the ZIP into your project res folder. Upload the 512 pixel file to the Play Console.
What image should I upload?
A square image at least 1024×1024 with the important part near the middle. Do not add rounded corners. iOS and Android round them for you.
Does it make adaptive icons for Android?
No. You get standard launcher icons. Adaptive icons need separate foreground and background layers, which you can create in Android Studio.
Why is there no transparency in the iOS icons?
Apple does not allow transparent app icons. Empty areas use your chosen background color, or white.
Are my photos uploaded anywhere?
No. HD Resizer runs entirely in your browser, so your images stay on your device. Nothing is sent to a server, and there is no account or watermark.
