I use acrobat pro dc on two different computers under Mac OSX.
When I sign a one page document with a digital signature on an external card (which I have to do every day due to work) I see that the laptop will store the signed PDF with a size of a few kb, whilst the desk computer will store the same file with a size of just over 2 mb. I refer to an identical text file digitally signed on each computer with the same card reader, card and digital signature.
I would obviously like to store these files with the minimum possible size (as my laptop is doing).
Surely this must be any configuration that differs in both computers...
