HTML to JSX Converter

A free online converter that transforms standard HTML markup into valid JSX — the JavaScript XML syntax used by React. Paste HTML from a design mockup, a Bootstrap snippet, or an email template and get JSX you can drop straight into a React component's return statement. JSX looks like HTML but follows stricter rules. This tool handles the conversions that trip developers up: class attributes become className, for attributes become htmlFor, inline style strings are converted to style objects with camelCased properties (font-size becomes fontSize), self-closing tags like <img> and <br> get the required trailing slash, and HTML comments are converted to JSX expression-block comments. Boolean and numeric attributes are quoted or wrapped as needed. The converter also handles less obvious cases: reserved words like class and for, data-* and aria-* attributes (which pass through unchanged), SVG elements that need namespace adjustments, and HTML entities that need proper escaping in JSX text. It produces clean, formatted output that respects indentation and can be further prettified with Prettier. Common scenarios: migrating an existing HTML site to React piece by piece, converting a Tailwind HTML prototype into React components, turning a CodePen HTML demo into a Storybook story, or cleaning up copy-pasted HTML from design tools like Figma's dev-mode export.
