Description: The Portable Document Format (PDF) is a universal file format invented in 1993 year by Dr. John Warnock from Adobe Systems. This invention caused the paper-to-digital revolution, because the main purpose of inventing PDF was to make document look the same way as the original version on any computer or device.
Technical Details: Every PDF file has a structure with fixed formatting and information about fonts and graphic elements on each page of a document. PDF document may contain different types of elements, such as buttons, hyperlinks, bookmarks, or annotations. PDF documents have complete description of a fixed-layout flat document that makes PDF similar to vector graphics file formats.
