Signature Pad is a zero-dependency JavaScript/TypeScript library for drawing smooth signatures on an HTML5 canvas using variable-width Bézier curve interpolation. It exports signatures as PNG, JPEG, or SVG data URLs and works in all modern desktop and mobile browsers.

Use cases

• capture user signatures in web forms
• draw smooth handwritten signatures on a canvas
• let users sign documents in a mobile browser
• export a signature as PNG, JPEG, or SVG
• add undo/redo and erase to a signature pad
• embed an e-signature widget without external dependencies

When to choose

• you need smooth, natural-looking signature capture in the browser
• you want a lightweight, dependency-free canvas drawing library
• you need multi-format signature export (PNG/JPEG/SVG)
• you must support both desktop and mobile touch input

When to avoid

• you need legally binding e-signature workflows with audit trails
• you need freehand drawing beyond signatures, like sketching apps
• you need server-side signature rendering outside the browser
