What's the Best Way to Sign PDF Documents in Chrome without Printing?

I recently used cudasign on my iPad at someone's recommendation to sign a PDF file. Worked fine, although my online signature was unintelligible.

Here's another option (a message from my boss):

The easiest way I know of to add signatures from a Mac is to save the document to PDF, open it in Preview then Tools --> Annotate --> Signatures --->  If you don't already have signatures stored, you use "Manage signatures" to get to an option of either scrawling your signature on the trackpad or holding up a signature to the Mac's camera to get that saved.Then any time you need a signature, just go to the one you want, it will appear on the PDF. Scale it and move it into place.Voila!

Thanks, I should have clarified.  For better or worse, I have a PC.

Doesn't matter if it's PC or Apple. Adobe has a signature tool. I don't have it in front of me right now, so I can't recite all the steps, but you can search for the instructions. You my need the Pro version. 

Thank you, but unfortunately Adobe Pro is needed, and it costs $12-14 per month.  I was hoping for a less expensive solution.

Thanks, Steven.  Unfortunately, HelloSign is no longer free after 3 signatures per month, but Adobe Reader looks like it has possibilities.  I'll give it a try. ETA It works!
