Questions
What is compared?
The text of each page, word by word. Images, fonts and layout are not compared.
What if text moved to another page?
Pages are compared one against the other, so moved text shows as removed on one page and added on another.
Can it compare scanned PDFs?
No. Scans are pictures without text to compare.
Is anything downloaded?
No. The result appears on the page and nothing is saved.
What are the limits?
Up to 100 pages and 100,000 words per PDF.
