Compare two PDFs for contract review
Legal and ops teams lose hours flipping between PDF versions. Side-by-side compare with linked scroll keeps both documents aligned so you spot clause changes faster — without emailing files to a third-party viewer.

Open toolWhy side-by-side beats print-and-highlight
iLovePDF and Adobe offer compare features, but many free workflows still mean printing two versions or scrolling one file while guessing what changed. PDFTwin renders both PDFs in your browser with PDF.js — no upload for viewing.
Enable linked scroll so page 12 on the left stays aligned with page 12 on the right. Toggle linked zoom when reviewing fine print in MSAs or SOWs.
Step by step
Open Compare PDF, add the older version on the left and the newer version on the right.
- Turn on linked scroll for synchronized reading
- Zoom in on redlines or table changes with linked zoom
- Use Split or Extract if you need to share only changed sections
When to use Compare vs Word redlines
Compare PDF is best when both parties share PDF exports. If you have editable Word track changes, stay in Word. For signed PDFs or scanned contracts, compare view is the practical choice.
