Nice tool!
Though personally I just use something like Xournal++ to edit the PDF (add text, add a signature image, etc.) and then use the following command to "fake scan it":
convert -density 150 input.pdf -colorspace gray -blur 0x0.1 -sharpen 0x5.0 -level 10%,90% -rotate -0.5 -sharpen 0x1.2 output-scanned.pdf
I don't even bother with making it look like scanned. Just adding a png signature with Xournal and that's it. Mostly government requests it so they never cared enough to complain.
