Add your signature image to PDF documents
Draw your signature above.
Place a signature image on the last page of a PDF — a scanned signature or a picture you drew — at the position and size you choose.
Sign a white piece of paper, photograph or scan it, and crop to the signature. PNG with a transparent background looks cleanest; JPG works too. Upload the PDF and the signature image together.
This adds a visible, drawn signature. It is not a cryptographic digital certificate signature — it shows intent visually, the same way printing and signing does, but it doesn't verify identity.
