File extension docx is best known for its use in Microsoft Word, a powerful word processor and authoring software that allows users to create and share documents. It is available as part of Microsoft Office and Office 365 subscription-based services.
Replacing the previously used binary .doc files, .docx files were introduced in MS Word 2007 and feature an Open XML formatting schema for more excellent compatibility with ZIP compression resulting in smaller files.
Microsoft Word 2007, Microsoft Word 2010, Microsoft Word 2013, Microsoft Word 2016, and Microsoft Word 2021 still use the same docx document file format.
MIME types used for Word docx documents:
application/vnd.openxmlformats-officedocument.wordprocessingml.document
Any text editor with the support of Microsoft Word docx format can open and edit .docx documents. Plenty of free open-source or commercial office suites and word processors are available for all major platforms.
Microsoft Word supports other document formats, so users can convert .docx documents to different formats using the File|Save as... menu option.
Some Third party word processors and converters also support formats from MS Word and can achieve docx conversion in the same manner.
