Compare PDF
Compares two versions of a document word by word. Added, deleted and changed text is highlighted and downloads as a Word report. Your files never leave your browser.
The PDF comparison tool finds the differences between two versions of the same document. See what changed in a contract that came back from the other side, which clauses were added to a new policy or which figures were updated in a quote, without reading both line by line. The text is compared sentence by sentence first and then word by word inside changed sentences, so reflowed lines and pages do not create false differences. Each difference shows its page in the old and new document; deleted words are red and struck through, added words green and underlined. The same list downloads as a Word report you can archive or share. Scanned pages are read with OCR automatically. Everything runs in your browser; confidential contracts are never uploaded.
How to use it

Frequently asked questions
Which differences are found?
All added, deleted and changed words in the text: figures, dates, names and clause wording. Font, colour, margin and image changes are not shown.
What if the page layout changed?
No problem. Because the comparison works sentence by sentence, moved lines or pages do not count as changes. Headers and page numbers repeated on every page are ignored.
Can I compare scanned documents?
Yes. Pages without text are read with OCR automatically. Depending on scan quality a few words may be misread and appear as differences; check important ones against the original.
Are my files uploaded?
No. Both documents are read and compared in your browser.
