About This Feature
Overview
Document Encryption in WPS PDF helps you protect PDF files by adding an open password or a permissions password and by limiting printing, copying, and editing.
Core tasks include:
- Set document encryption: Add an open password and a permissions password, then choose whether printing, content copying, and editing are allowed.
- Change or remove a password: Verify the current password, then update the existing password or remove encryption settings.
This feature is useful for contract sharing, internal document distribution, financial file storage, and personal privacy protection. It helps reduce unauthorized access risks while keeping document usage under control.

Overall Conclusion
WPS is a practical choice when you need to encrypt and control PDF permissions directly on Windows. If your work is centered on Word files, Microsoft Word may fit document-password scenarios better, while Adobe Acrobat is also suitable for broader PDF security controls.
