When this tool is useful
True PDF encryption is never simulated. Connect and audit an encryption endpoint before offering this feature publicly. The dedicated page keeps the task focused and provides a shareable URL you can bookmark for later use.
Privacy and file handling
This feature is designed for a separately configured server service. Before enabling it, use encrypted transport, publish a file-retention policy, restrict logs, and automatically delete temporary documents. The interface does not claim that processing succeeded until the service returns a result.
