How do you add a signature to a PDF?

The process is pretty easy: log in to your airSlate SignNow account, upload a document, open it in the editor, and use the My Signature tool. In the pop-up window, choose your preferred method. If you are using the service for the first time, you can create your electronic signature by drawing it with your touchpad or using a mouse, typing and selecting a handwritten style, or uploading it. All of them are legally binding and will be recognized as valid. If you already have saved signatures in your account, just select the one you prefer and place it on the sample.
