To all the questions above, the answer is to remove PDF restrictions.

You can see clearly the classification and the function of PDF restrictions.
How to remove PDF restrictions?
PDF Open Restriction – You set open restriction because you only want authorized readers to view the PDF file. EBook publishers enable open restriction of PDF eBooks to protect copyright, so that readers have to pay to get the authorization to view the book. If you write diaries and keep them in PDF, you can also lock the diaries with PDF open restriction out of privacy concern.
PDF Copy Restriction – You can't extract text, images, and other content of a PDF file with copy restriction by simply copy and paste. You may say, “I can still type them out if I do want to steal the idea”. Sure you can do that, but what about a PDF file with hundreds of pages? I believe nobody has the patience.
PDF Edit Restriction – Don't touch my book! This could be the heart voice of a writer who keeps his work in PDF. Yes. We use PDF to preserve content because we believe it's far more difficult to change a PDF file than a MS doc or a notepad txt. However, others can still temper with unrestricted PDF files with a PDF editor. To make PDF more secure, you need to apply PDF edit restriction.

PDF Print Restriction – Check out the PDF file for print restriction before you declare the printer guilty. This is the final defense of a PDF file. It won't let you make paper copies of PDF files. Publishers usually resort to this kind of restriction to prevent piracy.
 Ways to remove PDF restrictions Adobe Acrobat – If you've got Acrobat and know the password, you can easily remove all the four restrictions by typing in passwords in the Password Security – Setting window above. To open that window, click Secure button and select encrypt with password in Acrobat interface.
