App icon generator

Turn one square image into the full iOS and Android icon set, zipped for download.

The image stays in this browser. Icons are re-rendered at each platform size and packed into an uncompressed ZIP.

Source must be square, 512–8,192px, up to 32 MiB. iOS icons are flattened onto white (Apple requires opaque icons); Android keeps transparency. Adaptive-icon foreground/mask layers are not generated — these are plain square icons.

How to use

  1. Choose a square image (512px+).
  2. Pick iOS, Android, or both.
  3. Generate and download the ZIP.
