Formats for Application Images

The TIFF format is generally best for application images. It is lossless, and it can also keep your image's transparency and resolutions. Some images, though, consist only of basic shapes and colors. For these types of images, the PDF format can be better because it can be drawn natively at any resolution but can't contain some of the fancier graphical effects that bitmap images can.

You can also export your image as Source Code to generate code that will dynamically redraw your image's contents. Cocoa, Cocoa Touch, Core Animation, and Quartz code are great for applications for the Mac and iOS.
