DOC Document Format

DOC Converter

DOC and DOCX are the most common word processing file formats. DOC was primarily used by Microsoft for its Word program until 2003. Since 2007, Word has used DOCX as standard, although you can still open DOC files and can still save to the older format. DOC and DOCX are used for formatted text documents like reports, letters or resumes. They can include pictures, charts, and graphs, as well as plain or formatted text, and can also contain an editable template.

Word is part of Microsoft Office, which is available as a paid software application or accessed online with a Microsoft 365 subscription. Microsoft Office was designed for the Windows operating system, but you can also install Office apps on other operating systems like Apple’s macOS and Google’s ChromeOS. A basic free ‘Word for the web’ program is also available online for Microsoft account holders. DOC files are easy to share and print, and can be opened by most word processing programs, including LibreOffice, Apple Pages, and Google Docs, as well as by Microsoft Word.

DOCX Document Format

DOCX Converter

The DOCX format has been the standard format for Microsoft Word documents since 2007, replacing DOC. Microsoft Word is used widely in homes, workplaces and educational settings to create formatted text documents like reports, letters or resumes. As well as text, DOCX files can include pictures, tables, charts and embedded media, or can be an editable template.

The DOCX format has some advantages over DOC, including typically smaller file sizes and better security. DOCX is an Office Open XML file, making it easier to open DOCX files in other programs like LibreOffice, Google Docs or Apple Pages, with fewer compatibility issues. Word is part of Microsoft Office’s paid software application and is also available with an Office 365 online subscription. Microsoft Office was designed for Windows, but you can install Office apps on other operating systems. Microsoft also has a basic free ‘Word for the web’ programme for online Microsoft account holders.
