Need BATCH REMOVAL of Title (METADATA) from 872 separate PDFs - why isn't this possible?

Do I really have to download a third party's software to do this? I just need to remove the Title from ALL 872 separate PDFs I prepared. I can remove other metadata as well but really ir's title that is at issue. I don't want people knowing the title of the document from which I extracted the numerous PDFs. I tried "Action" and it is making me save each one individually after I load them all in there to have their metadata stripped.  I am not doing Javascript, please don't suggest it. Thanks in advance.
