1. Add both files
Choose the older version and the newer one.
2. Read the word changes
Added and removed words are highlighted so you can scan the edits.
3. Check the overlay
The visual overlay shows layout changes, such as moved images or a new table, that a text comparison can miss.
Questions
Does it work on scans?
The word comparison needs real text. For scans, run OCR PDF on both files first, or rely on the visual overlay.
