The WORD format most often means files created and saved in a text editor from Microsoft - Microsoft Word. Such files can have extensions .doc (DOC), .docx (DOCX), .rtf (RTF or Rich Text Format) and sometimes .txt (TXT). Editor versions from 97 to 2003 only supported the .doc extension. Beginning with Word 2007 and beyond (2010, 2013, 2016, and 2019), by default files are saved in the DOCX format — an enhanced version of DOC.
Today, the WORD format is the most common text file format. Its editing is supported in most popular text editors (WordPad, Google Docs, etc.). Features of this format allow you to store not only text but also many other elements - tables, images, and even videos.
File type: Document File extension: .doc, .docx, .docm Developed by: Microsoft Initial release: October 25, 1983The Portable Document Format (PDF) was created in 1993 by Adobe Systems in the PostScripts programming language and this document format was a digital analog of ordinary documents. At the beginning of its development, pdf documents were not popular, since this format was opened only in Adobe Reader (which was a very long time paid) and was not supported in other programs.
Documents in .pdf format can contain texts, images, videos, graphics, as well as the ability to encrypt and digitally sign a document. Today, PDF documents are very popular among users and are supported in any programs and on any devices, so the conversion from Word to PDF has become a very popular service.
