What makes a valid iOS app icon

The App Store marketing icon must be a 1024×1024 px square in PNG or JPEG, in the sRGB color space, fully flattened with no transparency and no alpha channel. Don't round the corners or add a drop shadow yourself — iOS applies the rounded-rectangle mask automatically. A wrong size or a stray alpha channel is a common upload rejection, so this tool exports a clean, opaque square every time.

How to use it

  • Drop in an image — square or not, any size
  • Drag, zoom, and rotate to frame it inside the square
  • Pick a target size and export a flattened PNG

Icon ready? Make sure the rest is too.
