I always use Preview to "sign" documents due to a lack of a scanner, but I've found in some cases, companies refuse to accept the document because they think it's not actually printed, signed with a pen, and then scanned...
Tools like this will skew and degrade the image in a similar way to a scanner so that it fits this ridiculous requirement
Have you tried signing a piece of paper with a pen and using Preview’s signature scan feature? It creates a very realistic looking signature in my opinion.
Yep, that is what I use. The signature itself looks completely handwritten (because it is), but the companies in question complain that it can't possibly be a handwritten signature because the document didn't look printed and scanned (???). It's slightly ridiculous, but not much I could do other than find a scanner/printer or "comply" with their document formatting requirement
