Questions
Which comparison should I look at?
Text changes lists the words that differ, ignoring layout: best for contracts and reports. Visual shows each page with the differing areas in red: best for drawings, layouts and scanned pages, which have no text to compare.
Why does a moved paragraph show as removed and added?
The comparison follows the text in order. A paragraph that moved elsewhere appears once as removed and once as added, the way most comparison tools show it.
Can I compare Word documents?
Save both as PDF first (Word’s “Save as PDF”), then compare the PDFs here. For plain text, use Text Diff.
Are my PDFs uploaded anywhere?
No. Your PDFs are opened and processed on your device, and the results are saved straight back to it. Nothing is uploaded. How to check.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
