Frequently Asked Questions
Does it compare the actual text or content of the two PDFs?
Yes. Each PDF's real embedded text is extracted page by page and compared, and the report lists exactly which pages are identical and which differ.
What does the comparison show?
Page count and file size for each document, plus which pages (by number) have identical vs. different text.
Does it compare visual layout, images, or formatting?
No — only the documents' embedded text is compared, not visual appearance. Two pages with the same text but different fonts or layout will be reported as identical.
