I have a perfectly fine scanned image of a signature. It is unnecessarily inaccurate to hold it in front of the camera instead of using the image directly.

How to enter the signature from the image file directly?

It can't be done directly.

Best authority I can find to back up this statement is Linc Davis, on the Apple Support Communities. - https://discussions.apple.com/thread/3667416

It is possible to create one that way in Acrobat Pro/DC, but I'm not then certain if that would then also work in Preview. It would depend if Acrobat creates the signature as a true Keychain Signature item.

It's not clear from Acrobat Help / Sign PDF documents but implies Adobe use their own cloud service to keep tabs on signatures rather than the Keychain.

  • How about just copying an image from the clipboard?? Well in any case i am going to ask a separate question for that. Apr 15, 2015 at 18:37
  • the only 2 ways to get a signature directly into Preview are 1) camera & 2) copy the Keychain entry from one Mac to another. That's it. Acrobat will import an image, but I don't think that is portable to Preview.
