I have some sewing patterns that I would like to share (and hopefully swap) but all of the PDFs have a

"This was purchased by John Doe john.doe@email.com #ordernumber - if you are not John Doe, please dob in the person you got this from to company@example.com so we can sick our lawyers on them"

sorta footer on every single page.

Obviously for privacy reasons (and because I don't actually want lawyers sicked onto me), I need to remove this footer.

These are often complex PDFs with more than a hundred pages and multiple layers.

I managed to successfully remove the editing password (not user/viewing password, just can't edit without password) with qpdf --decrypt. But removing that footer has left me at a dead end. I have even tried manually removing every single instance of those footers using Master PDF Editor but saving the file flattened it and you are no longer able to show/hide layers which is essential for correct printing. (Please don't ask me how many different PDF editors I have tried because it has been so so SO many I have lost count).

Not that I really want to have to manually edit this out on what could amount to over a thousand pages but searching for a command to remove a certain phrase has come up empty. Even Master PDF Editor doesn't seem to have a bulk remove or search and replace function (just search).

I use Linux btw.

You need to remove the edit password. Had success using Passware Kit to remove password. From there convert the pdf to word and remove what you need.

I was already able to remove the edit password with qpdf --decrypt. Most of the PDF editors I used, changed the PDF too much (e.g. added margins/padding) which ruined the very specific layout needed for the patterns to work. There has to be no changes to the PDFs apart from removing the 'footer' text :/
