To comply with dumb signature requirements. I needed this a couple of times. Usually it goes like this. You fill out a PDF form electronically, and add the signature via Adobe. Then you email it.

A lot of the times the recipient will complain that the signature was not handwritten. They want you to print it, sign it and scan it again. So you do this trick to make it look like you followed this process.

This website is not the first one that tries to achieve this. But I would not trust uploading anything to a random Web server though.

I usually do it via command line. You can use ImageMagick (i.e via the 'convert' command) to achieve the same result. It's very handy.
