DOCX is the most recent version of Microsoft Word’s DOC extension. Despite a number of updates and enhancements, the basic functionality hasn’t changed. The extension is still used for creating documents, editing and inserting various items like images, hyperlinks, tables, etc.

Unique and technical features of DOCX

Fierce competition on the market forced MS to implement Office Open XML. And the extension launched in 2007 automatically became the default format of Microsoft Office.

The key benefits of the updated version are enhanced efficiency, smaller file sizes and compressible images. However, despite obvious advantages, many users kept saving files in the DOC format due to certain compatibility issues.

Another implicit advantage of the DOCX format is that you no longer need MS Office on your device to open the document. Moreover, users received an opportunity to edit their documents online with Google Docs. Simply upload the file to your Google Drive and you are free to correct, share and leave comments on the document online.
