Create the signature appearance
You can set the appearance of your digital signature by selecting options in the Security Preferences. For example,
you can include an image of your handwritten signature, a company logo, or a photograph. You can also create
alternate signature appearances that you use for different purposes. For some, you may want to provide a greater level
of detail.
A signature appearance can also include information that helps others verify your signature, such as certificate
revocation status, reasons for signing, contact information, and more. By selecting these preferences, you add
options to the Sign Document dialog box that appears each time you sign a PDF.

1 If you want to include an image of your handwritten signature in the digital signature, scan your signature and
save it as an image file. Place the image in a document by itself, and convert the document to PDF.
2 Choose Edit > Preferences (Windows) or Acrobat (Mac OS) > Preferences, select Security on the left, and then
click New to create a new signature appearance.
3 In the Configure Signature Appearance dialog box, type a title for the signature appearance. When you sign a
document, you select the signature appearance by its title, so use a short, descriptive title.
4 For Configure Graphic, choose an option:
No Graphic Displays only the default digital signature icon and other information specified in the Configure Text
section.
Imported Graphic Displays an image with your digital signature. Select this option to include an image of your
handwritten signature. To import the image file, click File, click Browse, select the image file, click Select, and then
click OK (Windows) or Select (Mac OS).
