How to compare two PDFs
Three steps, about ten seconds.
- 01
Add both files
Drop the original and the changed version, together or one at a time.
- 02
Read the changes
Text changes shows removed words in red and added words in green, with the page they're on.
- 03
Check the layout
Visual overlay highlights anything that moved or changed on each page, including images and signatures.
Good to know
Text changes lines up the two documents and shows only what's different, with unchanged stretches folded away. It's the quickest way to review a contract or policy someone has edited.
Visual overlay draws both versions of each page on top of each other. Red marks what's only in the original and green what's only in the new version, so it also catches changes in pictures, stamps and layout.
Scanned documents have no text to compare. Use the visual overlay, or run both files through OCR PDF first.
Frequently asked questions
How do I compare two PDF files?
Add the original and the new version. Text changes lists only what's different; Visual overlay marks changes on each page in red and green.
Does it compare scanned PDFs?
Visual overlay works on scans. Text changes needs real text, so run scans through OCR PDF first.
Why does the whole page show as changed?
If content moved down (for example a paragraph was added above), the overlay marks everything below it. Use Text changes to see the real edits.
Is there a page limit?
No fixed limit. Very different files may be too different to line up word by word.
Are my files uploaded?
No. Both versions are compared in your browser, so they stay on your device.
