| Description | PDF is a file format developed by Adobe Systems for representing documents in a manner that is separate from the original operating system, application or hardware from where it was originally created. A PDF file can be any length, contain any number of fonts and images and is designed to enable the creation and transfer of printer-ready output. PDF is a cross-platform extension, which is necessary for the visualization of printed materials in electronic form. It is created by specialists from Adobe Systems using separate PostScript resources. PDF documents can exist separately from the OS or hardware tools with which they were developed. Files of this format do not have restrictions on the length, number of types and image options, as they allow you to embed various multimedia tools, scan-line and vector images. They are supported by Adobe Reader and many browsers, providing the plugin is installed. |

| Details | Each PDF file encapsulates a complete description of a 2D document (and, with the advent of Acrobat 3D, embedded 3D documents) that includes the text, fonts, images and 2D vector graphics that compose the document. They do not encode information that is specific to the application software, hardware, or operating system used to create or view the document. PDF supports color models CMYK, RGB, shades of gray, and also it has its own technical formats for performing the exchange of finished documents. Any file contains a description of a 2D or 3D document with all the necessary components (scan-line, vector graphics, text and more). The extension does not encode data associated with the software or OS that is used to develop and view the document. |
