Compare PDFs
Side-by-side text comparison of two PDFs
Compare two PDFs to spot the differences
When a contract comes back from the other side, or a document reaches its third revision, the changes are rarely flagged for you. Compare PDFs places two versions side by side so you can identify what has changed between them — a reworded clause, an altered figure, an added paragraph — without reading both documents line by line.
It is a real time-saver during contract negotiation, document review and version control, where a single quietly changed sentence can matter a great deal.
How to compare PDFs
Upload the two PDF versions you want to check, and the tool shows them together so you can review the differences between them. Comparing the documents visually helps you catch edits that are easy to miss in a quick read-through.
Both files stay private
The comparison runs in your browser. Neither document is uploaded to a server, so confidential drafts and contracts remain private.
