Two Types of Encryptions for PDF Documents

Encryption in documents is essential when they are to be protected from illegal access. Thus, PDF editors provide different options for adding encryptions within PDF documents. We shall be reviewing the two types of encryptions that can be added to the documents:

1. Open Password Encryption

The use of this type of encryption is helpful in situations where you have to enclose a complete document. You may use the option of open password encryption if you want to lock the document and send it to another user who can open it with the password communicated to them. This type of lock prevents the PDF from being read by any unauthorized user, which means that it is completely locked and useless if it does not open.

2. Permission Password

Permission passwords are a different form of encryption that puts security on some specifics of the PDF document. PDF editors provide the option of including the option of permission passwords that prevents other users from performing different actions. They might not be able to edit the document or change its formatting. You can also set encryptions that prevent them from printing the document or sharing it on any other platform.

In UPDF, there are also three Encryption Levels of open password and permission passwords, including 128-bit RC4, 128-bit AES, and 256-bit AES. The different levels refer to different protection levels. The 256-bit-AES is the highest level for the password.

Why You Need to Remove Encryption from PDF

Why would one move to remove the encryptions from their PDF document? The reasons provided below will help you understand the significance of removing passwords from the documents:

  • Putting restrictions on PDF documents prevents you from performing different actions, which might include copying content. If you have to copy some content to another file for another purpose, you won't be able to do it until the files are encrypted. Thus, it is essential to remove these encryptions from the PDF files.
  • To increase the accessibility of the document to other users, it would be best if you consider removing the encryptions from the PDF document. Removing the encryptions would help you easily share the document with other users. Being a professor, it would be tiring to provide every student with the password to the document.
  • If you wish to publish the document to another platform, you must have to remove the encryption from the PDF document so that it does not leave behind any problems during the process. As encryption prevents users from accessing or making changes in the document, this can get quite problematic.
  • Printing documents is impossible if the PDF documents have encryptions on them. The document won't accept any command since it is inaccessible. Thus, you will have to remove the permission password from the document to have it printed.


Removing encryption from PDF is not a problem for you now. You can use the methods above to unlock your PDF files in any situation.

If you know the password, the best way to do that is to use UPDF as it does not only help you remove the password but also change and edit the password in PDF. Moreover, it can give you more surprise like AI features that can help you summarize, explain, translate, etc.
