A few useful answers

Does the order of the files matter?

Yes. The first file is the original and the second is the revised version. Use the move controls to swap them before comparing.

What does the report detect?

The report compares rendered pages and available text. Its notes describe the visual resolution and tolerance used; review the source documents for subtle differences.

Can I compare PDFs with different page counts?

Yes. Added and removed pages are included. The two input documents can contain up to 100 pages in total.

When are my files deleted?

Your task shows the exact expiry time. Files are removed automatically after expiry, or you can use “Delete now” to remove them sooner.
