- 3Select Compare PDFs.
- 4Read the side-by-side report on the page, or download it as a file.
What the options do
- Ignore upper and lower case
- Treats "Total" and "total" as the same, so only real wording changes are flagged.
- Ignore extra spaces
- Different spacing or line breaks alone are not counted as a change. This is on by default.

Questions people ask
Are my files uploaded?
No. Both PDFs are read and compared in your browser. The report is built on your device.
What exactly is compared?
The text on each page, line by line, with changed words highlighted. Pictures, colours, fonts and layout are not compared.
Can it compare scanned documents?
Not yet. Scans are pictures of text, and reading them needs OCR. You will see a clear message if there is no selectable text.
What if the second version has extra pages?
Pages that exist only in one file are listed and marked as such. Pages are matched by their number.
What if text moved to another page?
Then both pages show as changed, because pages are compared by number. Read the highlighted lines to see where the text went.
