Icon and Image Sizes

Every app needs an app icon and a launch file or image. In addition, some apps need custom icons to represent app-specific content, functions, or modes in navigation bars, toolbars, and tab bars.

Unlike other custom artwork in your app, the icons and images listed in Table 39-1 must meet specific criteria so that iOS can display them properly. In addition, some icon and image files have naming requirements (to learn about naming these files, see App Icons in App Programming Guide for iOS and App Launch (Default) Images in App Programming Guide for iOS).

Web clip icon (recommended for web apps and websites)	180 x 180	120 x 120	120 x 120	152 x 152	76 x 76

For all images and icons, the PNG format is recommended. You should avoid using interlaced PNGs.

The standard bit depth for icons and images is 24 bits—that is, 8 bits each for red, green, and blue—plus an 8-bit alpha channel.

You don’t need to constrain your palette to web-safe colors.
