Metadata in PDF files can be stored in at least two places:
- the Info Dictionary, a limited set of key/value pairs
- XMP packets, which contain RDF statements expressed as XML

Many tools do not fully remove metadata, but just remove the link with in the metadata table. The data are thus still available in the PDF file itself.
While a lot of people rely on Exiftool to remove metadata, it actually does the same in PDFs. If you remove metadata with exiftool -all= some.pdf, you can always restore the data with exiftool -pdf-update:all= some.pdf.
There are several options to remove PDF metadata safely:
- Remove metadata with exiftool :
exiftool -all= some.pdf - Then remove ununsed objects with qpdf :
qpdf --linearize some.pdf - > some.cleaned.pdf
