Compare Word Documents
Open two versions of a Word document to see what changed: added words are underlined and removed words struck through, paragraph by paragraph. Download the comparison as a Word file with tracked changes.
ORIGINAL
Drop the original .docx
or choose one from your computer or phone
CHANGED
Drop the changed .docx
or choose one from your computer or phone
RESULT
The comparison appears here once both documents are open.
Runs entirely in your browser. Nothing you enter is sent to a server.
How to compare two Word documents
Open both versions
Drop the original .docx on the left and the changed one on the right.
Review the changes
Show the whole text or only the changed paragraphs, and ignore case or punctuation if they don't matter.
Download the comparison
Get a .docx in which every change is a tracked change you can accept or reject in Word.
Text, not formatting
The comparison looks at the words of headings, paragraphs, list items and table rows. Changes to fonts, styles or layout aren't detected, and the comparison document contains plain headings and paragraphs rather than the original layout.
When a file comes back without tracked changes
Colleagues and clients often edit a document without turning on Track Changes. Comparing the version you sent with the one you got back shows every edit, so nothing slips through.
Frequently asked questions
Are my documents uploaded?
No. Both files are read and compared in your browser.
Can I compare a Word file with a PDF?
Not directly. Convert the PDF to Word first, then compare the two .docx files; expect some differences that come from the conversion.
How is this different from Word's own Compare?
Word's Compare also checks formatting and keeps the layout. This tool works in any browser without Word and is quick for checking the text.
