PDF (short for Portable Document Format, meaning "Portable Document Format") is a file format developed by Adobe Systems for file exchange in a way that is independent of applications, operating systems, and hardware.

The portable document format is an electronic file format. This file format has nothing to do with the operating system platform, that is to say, the PDF file is universal whether it is in Windows, Unix or Apple's Mac OS operating system. This feature makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. More and more e-books, product descriptions, company announcements, network materials, and e-mails are beginning to use PDF format files.

Adobe's purpose in designing the PDF file format is to support the publication and distribution of multimedia integrated information across platforms, especially to provide support for network information publication. To achieve this goal, PDF has many advantages that other electronic document formats cannot compare. The PDF file format can encapsulate text, fonts, formats, colors, and graphics and images independent of equipment and resolution into one file. This format file can also contain electronic information such as hypertext links, audio and dynamic images, supports special-length files, and has high integration and safety and reliability.

For ordinary readers, e-books made with PDF have the texture and reading effect of a paper book, which can vividly show the original appearance of the original book, and the display size can be adjusted arbitrarily, providing readers with a personalized reading method.
