jPDFSecure is a software that allows protecting PDF documents against unauthorized viewing or printing. It relies on Java to encrypt PDFs and password-protect them.

Key Features


jPDFSecure uses a powerful encryption algorithm and it is nearly impossible to crack. There are three different levels of encryption: 40 bits, 128 bits and 256 bits for stronger protection.


As mentioned above, this tool helps protecting PDF documents with passwords. Only those who detain a right password can open it. The data's owner has a master password with full access and other users are granted a password with limited access.


jPDFSecure also allows the PDF's owner to grant different levels of privilege. For example, he can give permission to a user to open, print and share the PDF. But to another one, he can limit the access to viewing only.

Digital signature

It is also offering the possibility to create digital signature for PDFs in order to ensure the integrity of the document. This signature can be applied to existing files or new ones. When it is no longer needed, it can be removed easily with jPDFSecure.


  • Other versions designed for Mac OS X, Linux and Unix platforms are available on the publisher's Website.


  • This is a demo version.
