    Signature Pad

    Signature Pad

    HTML5 canvas based smooth signature drawing

    ...It's HTML5 canvas based and uses variable width Bézier curve interpolation based on Smoother Signatures post by Square. It works in all modern desktop and mobile browsers and doesn't depend on any external libraries. Demo works in desktop and mobile browsers. You can check out its source code for some tips on how to handle window resize and high DPI screens. You can also find more about the latter in HTML5 Rocks tutorial. This library is provided as UMD (Universal Module Definition) and ES6 module. When you modify width or height of a canvas, it will be automatically cleared by the browser. SignaturePad doesn't know about it by itself, so you can call signaturePad.clear() to make sure that signaturePad.isEmpty() returns correct value in this case.
