The PDF (Portable Document Format) format is designed for the convenient presentation of documents. It was created by Adobe Systems using the programming language PostScripts. Initially, pdf was supported only by official software, and even the program for viewing it — Adobe Acrobat Reader — was paid. However, later Adobe changed its policy and released the free version, and the format itself made open, allowing third-party companies and developers to use it in their programs.
Since then, the popularity of PDF has greatly increased, and the format itself has become practically the standard for the exchange of documentation and layouts for printing. Files with the .pdf extension can contain text information, fonts, images, and even video and animation. Editing and saving in PDF format are supported by many programs for working with documents.
