Why does Apple require square icons without rounded corners?

Apple's iOS operating system applies its proprietary continuous curve mask (squircle) dynamically at runtime. Uploading pre-rounded icons results in dark jagged artifacts around the corners.

Can my iOS App Store icon have a transparent background?

No. Apple explicitly rejects App Store submission graphics that contain alpha channel transparency. Our generator automatically fills the canvas with your chosen solid background color.

How do iOS 18 tinted and dark icons work?

Starting in iOS 18, the system dynamically tints launcher icons based on user wallpaper themes. Having clean, high-contrast foreground artwork on a solid background ensures seamless tinting.

What is the 1024x1024 marketing icon used for?

The 1024 × 1024 PNG is used by Apple for the App Store product page, search results, editor highlights, and the desktop App Store app.
