PDF24 is really a wonderful set of tools. Unfortunately, I had no luck with the secure PDF online. I uploaded, entered a password and unchecked permissions so the doc is not copied or printed etc. Is it a problem that it is a 295pp dissertation? Thank you for your help and your fine programs.

The password to open the PDF is optional. Just just do the security settings changes and create your secured PDF. Then the relevant options should not be useable in PDF readers.
