Compare DOCX Files Online
Inspect Word document revisions, editing changes, and draft updates directly in your browser.
How online DOCX comparison works
DiffQuery reads the text of both Word files directly in the browser, matches paragraphs between versions, and marks what was added, removed, or rewritten. You do not need Microsoft Word installed, and tracked-changes markers are not required - a clean export works just as well.
Compare two Word documents in three steps
Open the DOCX comparison tool, place the original and the edited file in the two panels, and run the comparison. Deleted sentences and new wording are highlighted in a merged view, which makes a final redline pass over a contract or proposal much faster.
Typical DOCX comparison scenarios
Check legal redlines between contract drafts, confirm that an editor's changes touched only the agreed sections, review student thesis revisions, and make sure a final report version does not silently drop clauses that were negotiated earlier.

DOCX comparison FAQ
Do I need Microsoft Word to compare DOCX files?
No. The comparison reads the .docx text layer directly in the browser, so any modern browser is enough - no Word installation and no plugins.
Are my Word documents uploaded anywhere?
No. Files are processed locally on your device; nothing is transmitted or stored on a server.
Will formatting-only changes be detected?
The comparison focuses on text content. Pure formatting changes such as fonts or colors are usually not flagged, which keeps the result focused on wording.
