A contract comes back with "minor edits," a report gets revised for the third time, or you just need to confirm two exports are actually identical -- Compare PDF highlights the differences instead of making you read both versions side by side.
How to compare two PDFs
- Open Compare PDF and upload both versions.
- Let it analyze the two documents.
- Review the highlighted differences.
- Download or note the comparison results.
Getting a useful comparison
- Compare the same document type. Comparing a scanned version against a text-based version of the same content works less reliably than comparing two text-based files.
- Focus on flagged sections first rather than re-reading the entire document -- that's the whole point of the comparison.
- Re-run after each revision round on longer negotiations, so you always know exactly what moved between drafts.
Frequently asked questions
What kinds of changes does it detect?
Text additions, removals, and edits between the two versions of the document.
Does it work on scanned documents?
It works best on text-based PDFs -- for scanned documents, running Scan to Editable first improves comparison accuracy.
Can I compare more than two versions at once?
Compare works on two files at a time -- for more versions, compare them in pairs.
Are both files uploaded to compare them?
No -- the comparison happens locally in your browser.
