Signature Pad

Forms

About

A canvas-less signature capture area with pressure or velocity-sized ink, touch/pen/mouse input, undo/redo history, native form field integration, and PNG, JPEG, SVG or JSON export.

Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Signature Pad to your project and fits it to your theme.

Code

How Signature Pad is used: the demo's code. The component's own source comes with a free account.
