"Theres a perfectly good topic at Portable Document Format so this topic should either be deleted or..."
The Portable Document Format (PDF) is the file format created by Adobe Systems, in 1993, for document exchange. PDF is used for representing two-dimensional documents in a device-independent and display resolution-independent fixed-layout document format. Each PDF file encapsulates a complete description of a 2-D document (and, with Acrobat 3-D, embedded 3-D documents) that includes the text, fonts, images, and 2-D vector graphics that compose the document.
