I'd like to sign pdfs using my signature. Unfortunately, Preview seems to require that you have a trackpad or a camera to do it. I have a Mac Mini, which has neither.
I do have my signature as a jpeg. In Acrobat on Windows, I could just import it and it worked. How do I do that in Preview?
With photo editors being what they are, it would be trivially easy to cut a signature out of a scanned signed document and put it on any other scanned document in a way that would be nigh-impossible to detect as fraudulent.
Yes, PDF editors would probably be able to snip out your signature. This, of all things, should not concern you.
If you don't want any borders, create a custom paper size and change margin size to 0 as shown below:
Name your custom paper size, use it and create PDF.
