How to remove (not extract) all attachment from a pdf on linux with some open source software?

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.

Just a guess, but can LibreOffice open, edit, then save as (or at least print to) PDF?

LibreOffice Draw can do that but you have to make sure the font and margins are right or else the formatting gets messed up.

Code Industry Master PDF does use open source tools. Sadly source code only available for paid user. 😂

Slightly shorter:

pdftk old.pdf cat output new.pdf

Im interested what people recommend. If you dont find any, what about just printing to another pdf file? Wouldnt that remove attachments?

I found much easier solution, pdftk A=oldpdf.pdf cat A output newpdf.pdf. This removes all metadata and also the attachments.

You might try printing the PDF as a PDF.

That worked but it removed bookmarks. I added solution to the post.

pdfimages is what you want, I believe. It's in the poppler-utils package in Debian.

Sorry, but that is for image extraction.
