If you've already added your signature or initials, just select it from the Sign options, and then click at the place in the PDF where you want to add your signature. Skip to the next step.
If you are signing for the first time, you see the Signature or Initials panel. Below is an example of the Signature panel.
- Type: Type your name in the field. You can choose from a small selection of signature styles; click Change Style to view a different style.
- Draw: Draw your signature in the field.
- Image: Browse and select an image of your signature.
- Save Signature: When this check box is selected, and you're signed in to Acrobat Reader or Acrobat, the added signature is saved securely in Adobe Document Cloud for reuse.
If you want to use an image as your signature:
- Sign your name in black ink on a clean, blank sheet of white paper. Sign in the middle of the paper so you don't photograph or scan the edges.
- Photograph or scan your signature. If you are taking a picture of your signature, make sure that the page is lit and that no shadows fall across the signature.
- Transfer the photo or scan to your computer. Acrobat/Reader accepts JPG, JPEG, PNG, GIF, TIFF, TIF, and BMP files. You do not need to crop the image. Acrobat/Reader imports just the signature if the photo or scan is fairly clean.
The creator of a PDF can encrypt the document with a certificate for verifying digital signatures. Certificates that you receive from others are stored in a list of trusted identities. This list resembles an address book and enables you to validate the signatures of these users on any documents you receive from them.
