PDF Security
Unlock PDF
Remove known PDF passwords when a user has permission to unlock the file.
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 protected PDF.
Enter the file password.
Download the unlocked copy.
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.
Questions
PDF conversion FAQ
Can this bypass unknown passwords?
No. Unlocking should only work when the user provides the correct password.
What backend should be used?
This page is wired to qpdf, an open-source PDF command-line tool.
