## 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 41-1 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][] and [App Launch (Default) Images][App Launch _Default_ Images]).

**Table 41-1**

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, for a total of 32 bits.

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