Comparing contract drafts to find every changed clause, definition, or provision is critical in legal review. Here is a free visual diff tool that catches every change.
Use PDF comparison when: reviewing a counterparty's redline, comparing a signed version to the original draft, checking if a "final" PDF matches the approved version, or auditing for unauthorized changes.
Upload the original contract as File A and the revised version as File B. Click Compare.
Switch to Diff view. Every pixel difference is highlighted in red — including changed words, reordered clauses, and modified numbers. Use Side-by-Side to read both versions in parallel with synchronized scrolling.
Tip: For contract review, focus on highlighted sections in red. Minor differences in pagination or formatting are normal between versions — focus on content differences in body paragraphs and defined terms.
Yes. The visual diff compares rendered page images — it works on any PDF including scanned contracts.
