PDF Encrypt Tool

PDF Encrypt Tool is a lightweight software application specifically designed to batch-protect PDF files with minimum effort.

Create a list with all the PDF files you want to protect

To import PDFs from your computer, file server or removable device, you can use the file or folder browser because PDF Encrypt Tool does not offer support for the 'drag-and-drop' feature. PDF files from the newly created list can be individually removed or you can clear the entire queue.

Set owner and user passwords

The program encrypts PDF files based on a step-by-step process that is very accessible for all level users and it doesn't require extensive computer knowledge.
Once you have decided which PDF files you want to encrypt, next you have the option of specifying a user or an owner password to open the documents. While an owner password gives you full access to work with PDFs, the user password may restrict your access to modify documents based on what permissions were enabled when the PDF was initially encrypted.

Configure encryption options

The encryption level of a PDF file depends on what version of Acrobat Reader was used to generate it. Thus, a 40-bit strength password is suited for Acrobat 3.x and 4.x, while the more secure 128-bit encryption can be used for Acrobat 5.x and higher documents.
Another notable feature is that you can configure permission parameters to allow users printing, copying, extracting and other editing rights, like modifying contents, filling or changing form fields.
Lastly, you can specify the saving directory or use the input folder location, as well as open the target location at the end of each task.

Reliable PDF encryption tool

To sum up, PDF Encrypt Tool is a handy piece of software that offers you the possibility to use its batch processing function to encrypt multiple PDF files at the same time. The interface it's very easy to understand which makes the application very accessible to novice users.
