PDF readers for many platforms are available, such as Xpdf, Foxit and Adobe's own Adobe Reader. While the PDF format can describe very simple one page documents, it may also be used for many pages, complex documents that use a variety of different fonts, graphics, colors, and images. PDF files are most appropriately used to encode the exact look of a document in a device-independent way. This feature ensures that a valid PDF will render exactly the same regardless of its origin or destination (but depending on font availability).Īnyone may create applications that read and write PDF files without having to pay royalties to Adobe Systems, however Adobe holds a number of patents relating to the PDF format and claims that it is an open standard, licensing them on a royalty-free basis for use in developing software that complies with its PDF specification. PDF files do not encode information that is specific to the application software, hardware, or operating system used to create or view the document. Each PDF file encapsulates a complete description of a 2D document (and, with the advent of Acrobat 3D, embedded 3D documents) that includes the text, fonts, images, and 2D vector graphics that compose the document.
