PDF Security
Protect PDF
Add password protection to a PDF with qpdf when installed on the server.
How it works
Convert files in three steps
The workflow is intentionally direct: upload, process, download. Ready tools run in the app server, while adapter tools are prepared for a production conversion provider.
Upload a PDF.
Set a password.
Download the encrypted PDF.
Privacy minded
Built-in tools do not write uploads to permanent storage. Add temporary object storage only when your production backend requires it.
Fast feedback
The interface keeps users informed with upload, processing, success, and error states instead of sending them to a dead end.
Ready to extend
Tool pages and API dispatch are config driven, so advanced providers can be added without rebuilding the site structure.

Is encryption implemented in this MVP?
Yes, through the qpdf command-line adapter when qpdf is installed on the server.
Should passwords be stored?
No. Passwords should only live for the duration of a conversion request.
