Add a Digital Signature to Images on Mac

 

Adding a Digital Signature

Among the most useful ways to use the Screenshot/Markup tool on Mac is to create a digital signature that can be reused. Consider using this digital signature method to sign off on documents, receipts, and more.

To access the tool, you can either:

1. take a screenshot of the image or document to which you want to add a signature:

   
    
   
   
   
   
   
   
    
2. or open the image file directly in the Preview application:

Adding a Digital Signature via your Camera:

Another great option for adding your signature is to use your computer’s camera to take a photo of your signature on blank white paper in black ink. This option, while it might take a little more time, results in a clearly legible signature.

To access it, select the add signature button and click on the "Camera" option:

 

You'll want to hold your paper up to the camera so that only the black ink is showing. It could take a few tries, but once you get the hang of it, this is the best option for adding a signature. The software will automatically mirror the image so that it shows up correctly. The result can be dragged and resized freely on your image, and will be saved for reuse:
