Adobe designed the PDF file format to support cross-platform, multimedia integrated information publishing and distribution, especially to provide support for network information release.

To achieve this purpose, PDF has many advantages that other electronic document formats cannot compare with. The PDF file format can encapsulate text, fonts, formats, colors, and graphics and images that are independent of device and resolution in one file. Files in this format can also contain electronic information such as hypertext links, sounds and dynamic images, support special-length files, and are highly integrated, secure and reliable.
