Compare Word Documents Online
Review DOCX revisions, editing changes, and updated drafts directly in your browser.
Choose the right Word versions to compare
Start with the last approved or reviewed DOCX file and the newer draft. Clear file labels help you avoid reversing the baseline and the version under review.
DiffQuery compares readable document text in the browser. It highlights textual changes, but it does not decide whether an edit should be accepted or explain the author's intent.
Review the changed text in context
Check additions and removals alongside the surrounding document preview. Pay particular attention to names, dates, amounts, headings, and references that matter to your workflow.
If the review depends on exact page layout, signatures, or visual formatting, inspect the final document separately; a text comparison is not a substitute for that check.
