Securing (Encryption): By password-protecting a PDF, you encrypt its contents. This means no one can open and view the file without entering the correct "user password." This is crucial for sharing confidential information such as contracts, financial reports or personal documents.
Unlock (Decryption): If you have a password-protected PDF and you know the password, you can use this tool to permanently remove the protection. The tool creates a new, identical version of the PDF that can be opened without a password, which is useful for archiving or when the security is no longer needed.
