PDF is not really meant for editing. It’s not even a data format.
Rather, it’s an executable program that has instructions like “select
this font” and “display this word in the selected font at this
position on the page” and “make a new page”.
You don’t normally edit executable programs, you compile them from
source. In the same vein, to get a modified PDF, you find the source
document from which it was produced, modify that, and re-export.
