The Portable Document Format (PDF) is a file format developed in the 1990s to present documents independently of software or hardware. Based on PostScript, PDF encapsulates all content needed to display a fixed-layout flat document, including text, fonts, images and graphics. PDF was standardized as an open format in 2008, and allows various interactive elements, rich media, 3D objects, encryption, signatures and metadata in addition to basic text and graphics content.
