Batch PDF encryption tool

The batch PDF encryption tool is a small but powerful software tool that can encrypt and restrict multiple PDF files in batches, including setting printing restrictions, prohibiting text copying, and adding independent opening passwords. Compared with other encryption tools, its most unique feature is to save the password of each file in the file list, so that users can view the password file through spreadsheet software such as Excel or the system's own Notepad.

Batch PDF encryption tool software features

First of all, the batch PDF encryption tool has a batch processing function that can encrypt and restrict multiple PDF files at the same time. This allows users to complete the encryption of a large number of files in a short time, improving work efficiency. Secondly, the tool offers a variety of encryption and restriction options to meet the needs of different users. Users can set printing restrictions to prevent unauthorized printing, thereby effectively controlling the distribution and dissemination of files. In addition, the prohibition of text copying function can prevent others from copying the contents of the file to other places, protecting the security of sensitive information.

​ ​ Most importantly, the batch PDF encryption tool generates an independent opening password for each file. This means that each file has a unique password, ensuring the file's independence and security. What’s more convenient is that the password file will save the password of each file in the file list. Users can use spreadsheet software such as Excel or the system’s built-in Notepad to view the password file. In this way, users can easily manage and find the required passwords, improving work convenience.

At the same time, the batch PDF encryption tool, like regular PDF encryption programs, provides a standard batch encryption mode that can use an open password to encrypt all PDF files so that the open passwords for the files are the same.
