よくある質問 (FAQ)

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.
