Creating a Signature File for Certificates
Signature images must be in .png or .jpg format. The actual signature will be displayed in black on a transparent background.
Use a black marker, such as a Sharpie™, and sign your name on a sheet of white paper.
Scan the signature into your computer.
Crop the image to a size of 2” x 5”.
Save it as to file in .png or .jpg format.
