How to compare two PDFs

  1. Add the original PDF first, then the new version.
  2. Nothing to set (enter a password if they have one).
  3. Click Compare and read the list of changes, or download it.
Are my files safe?

Yes. Your files are only used to create your result — they’re never shared and never used to train AI.

How are changes shown?

Lines starting with − are only in the first PDF; lines starting with + are only in the second. Each shows the file and page it came from.

Does it compare images or layout?

No — it compares the text. Moved images, colours or formatting changes aren't listed, and scanned pages (pictures of text) can't be compared yet.
