PDF (Portable Document Format. ) is the file layout manufactured by Adobe Systems. Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification. A PDF file consists primarily of objects, of which there are eight types: * Boolean values, representing true or false * Numbers * Strings * Names * Arrays, ordered collections of objects * Dictionaries, collections of objects indexed by Names * Streams, usually containing large amounts of data * The null object Objects may be either direct (embedded in another object) or indirect. Indirect objects are numbered with an object number and a generation number. An index table called the xref table gives the byte offset of each indirect object from the start of the file. This design allows for efficient random access to the objects in the file, and also allows for small changes to be made without rewriting the entire file (incremental update).

Pdf stands for Portable Document Format. An Adobe PDF file is very popular on the web because it preserves the graphical look of a document, unlike HTML, which adapts itself to different browsers and has limited support for fonts. PDF is a universal electronic file format, modeled after the PostScript language and is device-and resolution-independent. You must have Adobe Acrobat Reader to view PDF files which have (*.pdf) as file extension.

Anyone may create applications that read and write PDF files without having to pay royalties to Adobe Systems; Adobe holds patents to PDF, but licenses them for royalty-free use in developing software complying with its PDF specification.[3] The PDF combines three technologies: A sub-set of the PostScript page description programming language, for generating the layout and graphics. A font-embedding/replacement system to allow fonts to travel with the documents. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.

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.
