App Icons on iPad and iPhone

Technical Q&A QA1686

App Icons on iPad and iPhone

Q: How are the icon files in my application bundle used on iPad and iPhone?

A: Below are guidelines for handling icon files for iPhone-only apps, iPad-only apps, and universal apps.

If you don't provide artwork for one of the listed optional icons, the system will automatically scale one of your existing icon images to an appropriate size. It is strongly recommended that your application include artwork for all the icons listed, at the specific sizes needed.

Prior to iOS 3.2, icon images were required to follow a strict naming convention. These legacy names are still listed in the tables below along with example names for the more recent icons. Except for iTunesArtwork, icon images included in your app can have arbitrary names.

Note: iOS ignores the PPI (Pixels Per Inch) of icon images. You may author your icon images at any PPI but their width and height, as measured in pixels, must match the values in the tables below.

Important: iTunesArtwork icon images should be in png format, but name them without the .png extension.

Icons for iPhone-only Apps

iPhone-only applications use the following icons. Items marked with "Required" must be included.

Note: You should include images for the iPad-specific icons even if your app is not a universal app. If available, they will be used when the app is installed on an iPad.
