Could not find how to do it with qpdf or pdftk or even a gui tool.
Edit:
Solution pdftk A=oldpdf.pdf cat A output newpdf.pdf
This removes all metadata and also the attachments.

I forget exactly what I did, but I think I used okukar. It showed the attachments then it just selected them all and copied them to the desktop.
It might have been one of the web browsers, but I’m pretty sure it was okular as i couldn’t do it on windows.
If you have a better solution, please let me know.
I am talking about removing them from pdf. For extracting them this works
pdftk [pdf_file.pdf] unpack_files.I’ve used LibreOffice Draw before to remove content from PDF files without reprinting
