The comparison is visual, so it catches everything — text edits, moved images, layout shifts — regardless of how the PDF was made.
Documents with different page counts compare page-by-page; extra pages show against a blank.
Compare PDF — questions
Does it work on scans?
Yes — visual diffing doesn't need a text layer, which is exactly its advantage.
Are my files kept?
No — both files are processed in memory and never stored.
