This article focuses on how to remove password security from multiple PDF files by Adobe Acrobat program. Sometimes it is essential to access the stored data items and to print, edit as well as copy content from Portable Document Format files in absence of the person who actually added password security onto the PDFs. Moreover, erasing passwords from one file at a time is both tiresome and troublesome.

 

However, before discussing the method to delete password from PDF , it is necessary to know the types of password protection that can be applied to PDF documents. Then it is easy to devise ways to remove them. In the section below are discussed the types of passwords that are usually imposed as security on Adobe Acrobat portable files.


Kinds of Password Protection on PDF Files

 

The types of password that can be added in PDF files are:

 

  1. Document Open Password  -  Known as user-level protection password, it restricts unauthorized users from opening the PDF file and accessing the stored data items. With the Document Open password applied to the portable files, only users who know the user-password only can open the file.

 

  1. Permission Password  -  Permission password is also known as owner-level password. This kind of password actually restricts everyone except the owner of the document to print, edit or copy text, images or other content from the PDF file. The permission password, or Usage Restriction password also limits commenting on the Acrobat PDF files.


Removal of Passwords from Acrobat PDFs in Batch 


When the query is how to remove password security from multiple PDF files then make use of Acrobat Pro. With this program passwords can be removed from PDF files in batch. However, the kinds of passwords put on the documents must be known to make PDF unlocking successful. A user can put both Document password and Permission password either individually together. Hence, while perforing the process to remove password security from multiple PDF files by Adobe Acrobat, it is essential for the user who is deleting the passwords must know which kind of password was be used.

 

Case 1: When security on the documents are Open Password and not Usage Restriction password, then the Open Document password must be used.

 

Case 2:  When the security is Permission password and not user-level protection then the password that should be used to remove the security restriction is the Usage restriction password.

 

Case 3: When the Acrobat PDF files are protected by both the kinds of passwords that are user-level and owner-level then the password that should be used to erase the restriction is owner-level password.
