Portable Document Format (PDF) is an open standard for document exchange. The file format created by Adobe Systems in 1993 is used for representing documents in a manner independent of the application software, hardware, and operating system. Each PDF file encapsulates a complete description of a fixed-layout 2D document that includes the text, fonts, images, and 2D vector graphics which compose the documents. Today, 3D drawings can be embedded in PDF documents with Acrobat 3D using U3D or PRC and various other data formats.

In 1991 Adobe Systems co-founder John Warnock outlined a system called "Camelot" that evolved into the Portable Document Format (PDF).
Originally a proprietary format, PDF was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO 32000-1:2008.The ISO 32000-1 allows use of some specifications, which are not standardized (e.g. Adobe XML Forms Architecture). ISO 32000-1 does not specify methods for validating the conformance of PDF files or readers.
