Compare PDFs
See which words changed between two versions.
Free, no sign-up. It runs inside your browser: your files never leave your device.
Compare two PDFs and see which words changed between versions. Added, removed and changed text is marked, and you can save a marked-up copy to send for review.
How to use Compare PDFs
- Drop two PDF files: the original first, then the new version. Swap them with the arrows if needed.
- Turn on "Ignore case and punctuation" if those changes do not matter.
- Step through the changes with the next and previous buttons.
- Click "Save marked-up copy".
Questions
Does text that moved to another page count as a change?
No. Words are compared across the whole document, so text that only moved to another page is not a change.
Can I compare more than two files?
No. Compare two files at a time.
What do I get when I save?
The new version with every change highlighted and a note on what it was, plus a changes.txt list.
Are my documents uploaded?
No. Both files are compared on your device.
