Select filesWhy convert Word 97–2003 (DOC) to Word (DOCX)
DOC is a binary format that many web tools no longer read and that Word opens in restricted Compatibility Mode. DOCX is XML-based, smaller, and the native format of Word, Google Docs, LibreOffice and Pages.
The conversion runs through a full office engine on our server, which handles the old binary format’s quirks — embedded objects, fields, legacy numbering — better than lightweight converters.

About the formats
Word 97–2003 (DOC) · Legacy Microsoft Word document · .doc
The binary Word format used from 1997 to 2003; still opens in Word, but many web apps and phones cannot read it.
- DOC files are binary, not XML, so they cannot be inspected or repaired as easily as DOCX.
- Google Docs converts DOC on upload; Word opens it in Compatibility Mode.
- Macros can live inside DOC files, so some email systems block them.
RTF · Rich Text Format · .rtf
A 1987 Microsoft interchange format that almost any word processor can read: bold, italics, lists and tables, but no modern layout features.
- RTF is plain text with control codes, so it is safe from macros and easy to repair.
- Images are stored as hexadecimal text, which makes RTF files with pictures very large.
- Windows WordPad and macOS TextEdit both save RTF by default.
ODT · OpenDocument text · .odt
The open document format used by LibreOffice and OpenOffice Writer, and required by several governments for public documents.
- ODT is an ISO standard (ISO 26300) and fully documented, unlike DOC.
- Word can open and save ODT, but complex formatting may shift.
- Like DOCX, an ODT file is a ZIP archive containing XML.
Word (DOCX) · Microsoft Word document · .docx
The current Word format (since 2007): a ZIP of XML files that Word, Google Docs, LibreOffice and Pages can all open and edit.
- DOCX layout depends on the fonts installed on the viewing computer, which is why the same file can paginate differently on another machine.
- Converting to PDF freezes the layout so it looks the same everywhere.
- DOCX is part of the Office Open XML standard (ISO 29500).
