What's the problem with existing products? If you ask Google to find "sign pdf", you find 2 types of products: - Electronic/digital signature. It's a modern way to sign a PDF, but it solves another problem. Sometimes you need an exactly handwritten signature. - Handwritten signature. And here are the next options: - Draw your signature on screen. If you tried it, you know that it looks ugly, jagged, and not the same as a scan of a real signature. If you haven't tried it, just remember how you wrote something in Paint with a mouse. - Fake it with handwritten-like fonts. The problem is - it's not your signature. - Upload a picture. It could work if you already have a photo of your signature and have cleaned the background from it. It works, but it's not so fast and easy. I haven't found services which provide me with a handwritten signature like from a real document and make it easy and efficient.
