A PDF carries more than you typed: author, software, creation time, and often a client's address. PDF MetaClean audits first, showing exactly which tags are present, then strips the trailer /Info outright. Pages are never re-encoded, so the file stays byte-identical apart from the metadata. - see every tag before you touch the file - --verbose lists the real values - byte-level strip, no re-render - --self-check asserts the metadata is gone - one Windows .exe, zero dependencies, MIT
