Clears the owner-password flag that blocks printing, copying, or editing.

Remove signature

Strips a certification signature (DocMDP) that blocks edits, even without a password.

Password (only if the file asks for one to open)

Restrictions removed

Runs via QPDF compiled to WebAssembly, entirely in your browser. A PDF can restrict printing/copying/editing without a password (the "owner password" flag), and separately carry a certification signature (DocMDP) that blocks edits — this clears either or both, but won't open a file that actually needs a password to view.
