it's not left it's middle
Can you give some resources on how to do so.
I am talking about removing them from pdf. For extracting them this works pdftk [pdf_file.pdf] unpack_files.
pdftk [pdf_file.pdf] unpack_files
Could not find how to do it with qpdf or pdftk or even a gui tool.
qpdf
pdftk
Edit: Solution pdftk A=oldpdf.pdf cat A output newpdf.pdf This removes all metadata and also the attachments.
pdftk A=oldpdf.pdf cat A output newpdf.pdf
