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

          Yes but in my case the pdf file is big and I libreoffice draw hangs. Also i found another solution (added that to post).

        Oh in that case. Let me look up an open source tool I’ve used for PDFs before. It might be able to do it.

        It’s called pdfsam.

        I’m not sure if it can do what you are asking, but I think it will do the trick.

        You might be able to use the convert function of ffmpeg to extract the pages as png and then recreate a new pdf from the pngs that were extracted, but this may not work for your specific file.
