Frequently Asked Questions
Can I compare every page at once?+
Currently you compare one page pair at a time — pick the page number and click Compare. Step through pages to review the whole document.
What if the two PDFs have a different number of pages?+
You can still compare any page that exists in both documents — the tool limits page selection to the shorter of the two.
Does this compare the text or just the visuals?+
It compares the rendered visual appearance of each page pixel by pixel, so it catches any change — text, images, or layout.
