Frequently asked questions

What's included in the diff report?

A PDF with highlighted additions (green), deletions (red), and changes (yellow), plus a summary of all modifications.

Can I compare PDFs with different page counts?

Yes. Extra pages in either document are listed as additions or deletions. Matching pages are compared side by side.

How is this different from visual compare?

Diff report generates a downloadable PDF report with color-coded changes. Visual compare shows an interactive overlay in the browser.

Can I use the diff report for contract review?

Yes. Compare contract versions to quickly identify added clauses, removed text, and modified terms in a printable report.
