Rules for every App Store screenshot

  • 1 to 10 screenshots per display size.
  • File types: .jpeg, .jpg, .png.
  • No alpha channel or transparency. Our size checker flags both problems.
  • If your app’s UI is the same across device sizes and localizations, you only need screenshots for the highest required resolution; App Store Connect scales them down for smaller sizes.
