A quick example: two changes to a project update

Try sample documents in the empty workspace above, then choose Compare documents. The sample project update has the same three lines in both files, with two edits:

Deadline: Friday in the original becomes Monday in the revised document.
Status: Draft in the original becomes Ready in the revised document.

The comparison shows 2 changed lines, 0 added lines and 0 removed lines. These samples keep the same line order. In your own files, inserting or removing a line can make later lines appear changed because lines are matched by position.

How to compare two Word documents

Select an original .docx file and a revised .docx file, then choose Compare documents. Review the totals and changed lines on this page. The original and revised text are shown together so you can inspect each difference. Your original files are not changed.

What this comparison checks

Comparing another file type?

Use Text Compare for plain text or PDF Compare for two PDFs. Our file comparison guide also covers Excel, CSV and JSON.

Can I compare a Word document with a PDF?

This tool needs two .docx files. To check wording across different formats, follow the Word and PDF text comparison steps: extract each file to plain text, check the reading order and line breaks, then use Text Compare. This does not compare layout or images, and scanned PDFs need OCR first.
