The ASP.NET MVC Signature Pad is a graphical interface that allows users to draw smooth signatures as vector outline strokes using variable-width Bezier curve interpolation. It allows you to save signatures as images and vice versa. You can use your finger, pen, or mouse on desktop and mobile devices to draw your own signature.


Draw text as a signature using different font families and font sizes.
