What does the tool compare?
The text of both files, line by line. Green shows what exists only in the new version and red shows what exists only in the old version.
Does it work with scanned PDFs?

Do layout, color, or image changes show up?
No. Only text differences are shown.
Is it really free?
Yes, 100% free. No sign-up, no subscription and no usage limits. All Tools123 are free.
