How to remove (adobe) digital signature from PDF
By John Parsons •
This follows up my previous question: How to check if PDF has been digitally signed?.
Just in doubt a document has been digitally signed (e.g. with Adobe), how to remove the signature?
In particular, does "print to file" remove it?

If you've got ghostscript installed try:
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=%stdout% -c .setpdfwrite -f locked.pdf > unlocked.pdfThat would remove signature. If the pdf file has a password, then add parameter:
-sPDFPassword=$PASS...and password would be disabled.
