DiffFind FEATURES
PDF Comparison — Compare PDF Documents and Redline Two PDFs
Load two versions of a PDF and see exactly what changed. DiffFind highlights the differences on the page, so you can review a revised contract, policy, or report without reading both documents line by line. Then use optional AI analysis to understand whether a change affects the meaning.
How it works
Compare the versions.
Run the comparison to find every difference between the two documents.
Review the redline.
See changed, added, and removed text highlighted on the page.

A revised lease agreement
Changed rent, fees, and lease dates are highlighted in the redlined PDF.
Why PDF Comparison is useful
Use PDF comparison to review contract revisions, lease renewals, policy updates, invoices, reports, and any document where a small change can matter.
Instead of hunting for edits by eye, start from a highlighted list of what changed, then check each one against the page.
Need to compare plain text or spreadsheets instead? Try Text Compare, Excel Comparison or Word document comparison. To understand what a wording change means, see Semantic Diff or Semantic Search.
DiffFind lets you compare PDF documents with a precise, deterministic comparison, then ask AI semantic analysis whether a revised clause really changed the terms. For other file types, see AI document comparison.
