About Microsoft Word
Microsoft Word documents come in two formats: DOCX (Office Open XML, 2007+) and DOC (legacy binary, 1997-2003). DOCX is the modern standard, storing content as compressed XML files inside a ZIP container. It's more compact, less prone to corruption, and easier for third-party applications to parse. DOC is the older binary format, primarily encountered in legacy documents created before 2007.

Both formats support rich text formatting, styles, tables, images, headers/footers, and change tracking. For final distribution, archival, or cross-platform compatibility, converting to PDF ensures the document appears exactly as intended regardless of the viewer's software or operating system.
