Three methods for Remove Security from PDF Files
Sometimes we will suffer following problems for Adobe PDF Users.
Question 1:How to Remove PDF Copy Protection from PDF Files
Question 2:How to Print Secured PDF files?
First we know that a secure PDF file enforces copyright laws with features to prevent reproduction or distribution by other users. The owner or creator of a PDF file can restrict user access, printing, text copying and document editing with password protection. Another form of security is a digital certificate, which encrypts PDF files so that only certain users can open them. The content of a PDF file can also be encrypted, ranging in breadth from just the attachments to all document data.
PDF files can be encrypted with password to protect copyright, which are widely accepted and used by writers. However, protected PDF files also bring inconvenience. For example, you read a PDF eBook and want to copy some sentences so that you can quote in other places. Unfortunately, the PDF is protected with owner password that prevents you from copying. What should you do?
Method 1:
To copy protected PDF files, you need to remove the password from encrypted PDF files first. Doremisoft PDF Password Remover is an efficient PDF tool that developed to remove PDF copy protection. There are two versions provided to meet different user experiences: PDF Password Remover and PDF Password Remover for Mac.

Click “Add Files” to load PDF files into the control panel, you can select many PDF files and import them at one time. For the user password protected PDF files, you need to input correct password when adding them, which make sure you have legal rights to unlock the password.

4.Change encryption settings instead of completely unsecuring the PDF file by choosing the Show Security Properties menu item under the Secure button, rather than choosing the Remove Security option.
Encrypt different document contents or change the encryption algorithm, if you desire, and then hit Next.Check a recipient’s trusted identity, change a recipient’s permissions or remove recipients if you want to alter these items, then click Next.Click Finish and OK to save your changes and close the document properties window. Save the PDF file to implement the changes you have made.
