PDF copyright protection software encrypts and protects PDF and UPDF files to ensure the security of PDF files.

PDF Unshare is a free PDF copyright protection software, which encrypts and protects pdf and UPDF files. In addition, users can set permission and authorization settings to prevent unauthorized users from printing, editing, and copying sensitive information.

For organizations looking for easy-to-use PDF encryption solutions to protect sensitive data, PDF Unshare Pro does not use passwords to protect PDF files because they can be easily shared or deleted by PDF password-remove programs. On the contrary, PDF Unshare Pro protects PDF files by a separate encryption key, which is relayed from the webserver to the authorized device and encrypted in the key store of the local machine. The key store is locked to a single computer, so it cannot be copied and moved to another computer.

As more and more organizations worldwide turn to user-friendly and secure PDF file encryption software, PDF Unshare provides users with a data-centric security method, which is practical and easy to use. In addition, PDF Unshare opens the door for future joint innovation, which will help users protect data wherever they share data while reducing risks.
