Webform Signature support added to FillPDF for Drupal 8

Thanks to a patch from Khaldoon Masud, version 8.x-4.9 of FillPDF can now stamp images from Webform 8.x-5.x signature fields into PDFs (when using a backend that supports image stamping).

Use the token corresponding to the Webform signature field when setting up your mapping, and FillPDF will do the rest.
