How to Compare Two PDFs and See What Changed

Find added, removed and changed text between two versions of a contract, a quotation or a report. Free and private.

Someone sends a “final” contract again. Did anything change? Reading both side by side is slow and easy to get wrong. A comparison tool does it in seconds.

Steps

  1. Open Compare PDFs. Add the old version on the left and the new one on the right.
  2. Read the summary: how many lines were added, removed or changed.
  3. In Text changes, changed words are highlighted so numbers and dates stand out.
  4. In Page view, see where a page looks different. This also works for scans.

What to check in a contract

  • Amounts, dates and percentages.
  • Names and addresses.
  • Clauses about payment, penalty and ending the agreement.

Keep a record

Download the list of changes as a text file, or the page view as a picture, and keep it with the contract.

Both PDFs stay on your device. Nothing is uploaded.

Frequently asked questions

Does it work on scanned PDFs?

Use the Page view, which compares how the pages look. The text comparison needs real text.
