What is a .DOCX file?
The DOCX format (short for Microsoft Word Open XML Document) is a word-processing document format that uses lossless compression, so every detail is preserved exactly with no loss of quality. Its text and formatting remain fully editable after you open it. DOCX is an open, royalty-free standard.
