    When you receive a PDF document by email that you must sign, the process of printing out the file, signing on the dotted line with a pen, scanning the signed document and sending it back can be a rather tedious task. Fortunately, Apple introduced the ability to electronically sign a PDF document using Preview, a program that comes preinstalled on every Mac, on OS X Lion or later.

    The steps involved to electronically sign a PDF using Preview on Mac are quite simple and will save you valuable time, especially if you have multiple documents, contracts, forms or other paperwork to sign. If you are worried that your virtual signature will look bad, rest assured that you can create your signature by using the trackpad or holding up your signature on paper to a Mac's built-in iSight camera.

    I've never figured out how to do this if you don't have a camera or trackpad. A simple image import feature would be nice but there isnt one last time I tried

    It's so clever to use Force Touch to show the varying pressure you put on your signature. Can't wait to try out the new MacBooks

    "Click on the briefcase icon"

    Pretty sure that's a tool box

    Just to be "that guy"...

    While people often do refer to this as a "digital signature", it really isn't anything of the sort. A digital signature is a cryptographic entity that at some level proves that you are indeed who you claim you are. It generally doesn't involve anything resembling your on-paper signature.

    Anyone can append a rasterized/digitized version of your written signature to a document - it doesn't have to be you. With a real digital signature, though, that can't happen unless you are sloppy with your private key(s).

    This is exactly what I was going to say. I thought this article would be about RSA.

    You beat me to it. Briefcase? Someone needs a rest break.

    Based on what it looks like it can really be interpreted either way.

    Nice awareness-raising article but I am not sure why this is a Macrumors post. I've been signing PDFs on my 2013 mba for a while now so it isn't a brand new thing. Maybe new to Yoshemite though.
    Yes you can import images. Just drag and drop the signature image file onto the PDF. You might need to be in signature mode first, I can't remember.

    No, a PDF in Preview will not allow you to import/drop an image into it. The PDF has to be converted to an image, then you drop the image into it and convert back to PDF.

    If you believe this to be wrong perhaps you could create some step by step instructions, because my own testing and a whole lot of googling and no one else has found out how to do this.

    Well, while repairmen use toolboxes, I am sure some artists carry their tools in a briefcase. :)

    Why the need to create a new thread about an old feature if nothing about its signature rendering quality was updated afaik?

    One of those "The More You Know..." PSA type of things perhaps?

    Yes, this capability has been in Preview for a long time. At least since Mavericks and I think even before that. There is something that changed though. You used to be able to edit (move, resize) or delete the signature later; now, once you save and close the file it's permanently baked in.

    If you can get a hold of a Mac that has a camera and have access to their Keychain, you can capture the signature there, then transfer it over to your Mac with this lack. Just make sure you delete it off the old one when you're done. Or if you have a few Macs and want to keep signatures handy on all of them, this is a neat method.

    Has anyone actually been able to create a decent signature with the trackpad? It seems more gimmicky than useful to me and I doubt that it can be used for more than a simple paraph. You might as well draw an ‘x’, it wouldn’t make a difference legally anyway.

    With a stylus, I have a long name and it came out decent and legible.
