Why Manage PDF Security?

• Locking a PDF: Protects confidential information like financial reports or personal records, ensuring only authorized people can view it.
• Unlocking a PDF: Removes password restrictions when security is no longer needed, making the document easier to access, share, and edit.
• Secure Collaboration: Safely share documents by locking them, and then allow easy access by unlocking them when appropriate.
