Frequently asked questions
Does Compare PDF detect layout or image changes?
It compares the text content of both PDFs — visual or image-only changes aren't highlighted, only differences in the extracted text.
Can I compare more than two PDFs at once?
Compare PDF works with two files at a time. To compare more versions, run the tool again with different pairs.
