Common questions
Does it work on scanned PDFs?
Pages without extractable text show no word differences. Run OCR PDF first to add text.
What if one file has extra pages?
Pages that exist in only one PDF cannot be overlaid, but the summary shows the page counts.
Are my files combined?
No. Both stay as they are, and you get a separate report.
