Password Protect PDF
The Password Protect PDF utility provides robust client-side encryption for sensitive documents, preventing unauthorized opening, inspection, or extraction. Whether locking confidential salary reviews, proprietary IP documents, or medical records, you can set strong access passwords in seconds.
Because encryption keys and document payloads are generated and computed locally using modern cryptographic Web APIs, your master passwords and document contents are never transmitted over the internet, stored in logs, or vulnerable to server interception.
