- Review differences visually, including dates, numbers and missing pages.
What this tool actually does
Side-by-side viewing helps a human compare appearance. It is not an automatic legal redline, semantic diff or proof that every change has been identified.
Choose the controls for your document
Add the intended two versions in a clear order. Match zoom and corresponding positions, and keep a short list of differences as you review.
Before your first export
For revised terms, compare matching sections rather than assuming the same PDF position contains the same paragraph. An inserted page can shift every later page without changing their actual content.
The same position shows unrelated pages
One version may contain an inserted or removed page. Align by headings or content instead of assuming page 4 matches page 4.
Check the result
This is a comparison workspace, not guaranteed automatic semantic or legal difference detection.
Keep the original. When this task produces a file, reopen the download in the application where you will use it and inspect the affected pages. An illustration explains the operation; it is not a recorded processing test.
Practical tips
- Add the intended two versions in a clear order. Match zoom and corresponding positions, and keep a short list of differences as you review.
- One version may contain an inserted or removed page. Align by headings or content instead of assuming page 4 matches page 4.
- Zoom into the relevant area and check source text when possible. Use a dedicated text-diff workflow for exhaustive wording comparison.
