How to compare two PDF files and find the differences
The other party sent back an amended contract and you don’t know exactly what they changed? Instead of reading both documents line by line, upload both versions – PDFowo shows the added, removed and changed words, or the differences in how the pages look.
- Upload two versions
Drop the older version in the “Version 1” box and the newer one in the “Version 2” box.
- Choose a mode
“Text” compares the content word by word, while “Page appearance” compares the pages as images.
- Review the changes
The list shows every difference, and the “Previous” and “Next” buttons take you to each change highlighted in both documents.
Which mode to choose
- Text – contracts, terms, offers and other text documents; it works even when content has moved to another page
- Page appearance – scans, technical drawings, graphic designs and documents without a text layer
Fewer false alarms
The “Ignore case and punctuation” option hides minor differences such as commas or capital letters, so the real changes are easier to spot.
Frequently asked questions
Is the comparison free?
Yes, viewing all the differences is free. You can also download a PDF report with the changes highlighted.
Can I compare scanned documents?
Yes, in “Page appearance” mode. Text comparison needs documents with a text layer.
Are the compared contracts safe?
Yes. Both files are compared in your browser and are not uploaded to a server.
