Good uses for PDF comparison
- Rental and employment agreements: check that the “final” copy matches what you negotiated before you sign.
- Quotations and invoices: spot changed amounts, quantities or terms between versions.
- Policy documents and terms: see what a company actually changed in its updated terms.
- Proofreading: confirm a designer's final PDF has every correction you asked for.
Frequently Asked Questions
What's the difference between text and visual comparison?
Text changes compares the words in both files and highlights exactly which words were added, removed or edited, even if the layout moved. Visual overlay draws the same page from both files on top of each other and colours anything that differs. It catches changes in images, signatures, stamps and formatting that a text comparison can't see.
Why does a whole paragraph show as changed when only one word is different?
The paragraph is marked as changed, but look inside it: the specific words that differ are highlighted in red (original) and green (new). Everything else in that paragraph is the same.
Can I compare scanned PDFs?
Use the visual overlay. Scans have no text to compare, but the overlay still shows where pages differ. Small shifts between two scans of the same paper show up as outlines, so it works best for files produced digitally.
Are my documents uploaded?
No. Both PDFs are read and compared in your browser, which matters for contracts, agreements and other confidential drafts.
Can it compare a Word file with a PDF?
Convert the Word file to PDF first with the Word to PDF tool, then compare the two PDFs. Or paste both texts into the Text Compare tool.
