hello to all, I was searching how to protect a pdf file and come here to digital editions.
I understand what it does and I want to protect my PDFs using this tool, but have no idea how to do it. Did some research but could not find the answer.
anyone could be clarify me?
thanks and regards,
want to add more info about my idea. I use a Mac and my file is already in PDF, no way to get the original file.
