Remove Digital Signatures from PDF

Once a PDF is digitally signed, it becomes locked — you cannot merge, edit, or modify it without breaking the signature validation. This blocks legitimate workflows like document assembly or re-archiving.

Strip all cryptographic digital signatures and certificate-based locks from PDFs, returning them to a standard, fully editable state. The document content remains completely intact.
