Is it legally valid?
This adds a visible signature image, which is what most forms, letters, leases and everyday agreements ask for. In many countries an electronic signature like this is accepted for everyday agreements, but rules vary, and some documents need a certified digital signature or a wet signature. Check with whoever asked you to sign.
After signing
