Questions
▸How do I keep my signature from being cut off?
Set the shape option to Keep whole image. The signature is fitted inside the size you entered and the extra space is filled with white.
▸My signature looks light after reducing the size. What can I do?
Sign with a darker, thicker pen on plain white paper and take the photo in good light. A higher KB limit also keeps it sharper.
▸Is the file uploaded?
