How to Use?

XenArmor PDF Password Protector Pro  is very easy to use.

Please follow simple steps to protect your PDF file

  1. First, select type of operation (single file or folder)
  2. Next drag & drop or select your PDF file/folder using browse button
  3. Now set the open password for target file
  4. Optionally, you can choose restrictions such as copy, modify, print etc.
  5. If you set restrictions then you have to set permission password. By default, it will use open password for permission password as well. You can enter different one.
  6. Finally, you can click on “Protect PDF” and your selected or all PDF files in folder will be password protected as shown below,


Please note open password is also referred as user password and permission password is also referred as owner password in general.

Here are different scenarios of setting one or both of these passwords,

1. Set open password and empty permission password

In this case, by entering open password, target PDF file can be opened and there will not be any restrictions (copy,edit,print etc)
Here anyone with open password can have full access to PDF file.

2. Empty open password and set permission password

In this case, anyone can open target PDF file but cannot copy, modify or print. However by entering permission password, one can bypass all such restrictions.
Please note in most cases, special softwares like PDF Password Remover Pro can completely remove such password & restrictions. Hence this is not geat protection option.

3. Set both open and permission password

In this case, if the user opens target PDF file by entering open password then he/she can view the contents but cannot copy, edit or print. However if the user opens file by entering permission password then he/she can perform all operations.
With this protection option, you can give open password to those who needs to only view PDF file and give permission password to one who needs to have complete access to it.

PDF Password Protector Pro also automatically installs right click context menu. This allows you to right click on any PDF file and click on “Protect PDF” to quickly protect PDF file.

Also note that Personal Edition supports up to 25 files while Enterprise & Ultimate Edition supports up to 100 files in folder.
Unlimited Edition supports unlimited files in folder.

Below are the detailed explanation for each of these settings,

Target PDF Encryption Type

Here you can select encryption type (RC4, AES) for target PDF file based on compatibility with Adobe Acrobat.
AES-128 or AES-256 is recommended.

Set Suffix for Target File

By default it automatically sets suffix _free to target file. Here you can set new suffix text or disable it completely.

Ignore Files with above Suffix in Folder

In folder mode, by default, it will skip all PDF files with above suffix. This is useful to skip files whose passwords have already been removed.

Remember the Input Password

By default all input parameters including source file, target file, password (encoded) are stored in Settings (settings.db) file. So that you don’t have to enter it next time.
However for security reasons if you want to prevent storing password then you can uncheck this setting.

Enable PDF file right click context menu

This option helps you to enable or disable PDF file right click context menu. Once enabled, you can right click on any PDF file and select “Remove Password” menu option. By default it is enabled for all editions except for Unlimited Edition.
