How to Remove Password Protection from PDF Files

Posted by on .

I have a bunch of PDF eBooks with copy protection on my pc. It’s inconvenient for me to print or edit. I ever met a PDF document which could be opened or copied, but there were a couple of pages that I could't open. I could see them on the bookmark toolbar and click them, but it won't show up the pages. So I will share how to remove PDF password security restrictions on printing, editing, and copying a PDF file with readers.

Difference between user password and owner password

The user password is known as a document open password. Users must type in the password you specify to open the PDF for viewing, editing, printing, etc.

Enter User Password

The owner password is known as a master password or permissions password. Recipients don’t need a password to open the document. But they must type the permissions password to set or change the restricted features. For an instance, when you convert password protected PDF files to EPUB format, the Calibre will alert a window to forbid you to change files type as follow.
