This is an easy way for you to add your signature to any PDF document. Using the built in camera in your Mac and the Preview App, you will be able to capture and save your signature.
1. Open the PDF file you need to sign in Preview.
Click on the toolbox icon and then the signature icon.
2. Click on Create Signature, Then Camera
3. On white paper, sign your name and hold it up to your computer’s camera and align it to the line shown. If you are not satisfied with the result, click the “Clear” button and try again.
Your signature will be inverted. Preview will automatically switch this.
4. Click Done.
Click on your signature to insert it into the document. You can now move and resize as needed.
Preview automatically saves all the signatures you create in a list for you to insert into any document or files that you open with Preview.
