Examples

1. Strict Internal Sharing Protection

Project Manager

Background: Sharing a highly confidential project roadmap with stakeholders.
Problem: Need to ensure only authorized personnel can open the file and prevent any unauthorized copying or printing.
How to Use: Upload the document, set an open and owner password, and disable both printing and copy permissions.
Example Config: openPassword: 'DemoOpen@123', ownerPassword: 'DemoOwner@123', allowPrinting: false, allowCopy: false, encryptionLevel: '256'
Outcome: The PDF is fully encrypted and requires a password to open, with all editing and extraction features disabled.

2. Readable but Non-copyable PDF

Legal Consultant

Background: Providing a draft contract to a client for review during a meeting.
Problem: The client needs to print the document for reference, but the text must remain protected from digital extraction or modification.
How to Use: Upload the contract, set passwords, enable printing, but keep the copy/extract permission disabled.
Example Config: openPassword: 'TeamRead@2026', ownerPassword: 'TeamOwner@2026', allowPrinting: true, allowCopy: false, encryptionLevel: '256'
Outcome: The recipient can open and print the document but cannot copy the text content into other applications.
