Remove All Signatures from a PDF
1. Using Ghostscript
Re‑distill the PDF to strip all digital and form‐field signatures:
gs -q -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -sOutputFile=unsigned.pdf signed.pdf
2. Using qpdf
Flatten forms and annotations:
qpdf --flatten-forms --flatten-annotations signed.pdf unsigned.pdf
3. Using pdftk
Flatten form fields (stops tracking signature fields):
pdftk signed.pdf output unsigned.pdf flatten
