Frequently asked questions
Can this crack an unknown password?
No. You must know the valid user or owner password.
Is the password stored?
No. It exists only in the page while the local worker processes the document.
Does unlocking change page quality?
No. qpdf removes encryption without rasterizing or recompressing page content.
Can I unlock any encrypted PDF?
It supports encryption formats recognized by the bundled qpdf engine; damaged or certificate-encrypted files may not work.
