HTML to JSX Converter

Convert HTML to JSX with automatic attribute conversion.

How to Use the HTML to JSX Converter

Paste your HTML into the input box. The tool instantly converts it to valid JSX that you can drop straight into a React component.

What Gets Converted

  • class → className — the most common JSX difference
  • for → htmlFor — required on label elements in JSX
  • style strings → style objects — e.g. style="color: red" becomes style={{ color: 'red' }}
  • Self-closing tags — br, hr, img, input and other void elements get a closing slash
  • Event handlers — onclick becomes onClick, onchange becomes onChange, etc.
  • Attribute casing — tabindex becomes tabIndex, readonly becomes readOnly, and more

Everything runs locally in your browser. No HTML is sent to any server.

Frequently Asked Questions

What HTML attributes are converted?

The converter handles class to className, for to htmlFor, style strings to style objects, all common event handlers (onclick, onchange, etc.), and casing corrections like tabindex to tabIndex, readonly to readOnly, and many more.

Does it handle inline styles?

Yes. CSS style strings are converted to JavaScript style objects with camelCase property names. For example, background-color becomes backgroundColor and pixel values are converted to numbers.

Are self-closing tags handled?

Yes. Void elements like br, hr, img, and input are automatically converted to self-closing JSX tags (e.g. <br> becomes <br />).

Is my HTML uploaded anywhere?

No. All conversion happens in your browser using JavaScript. Your code never leaves your device.

Does it convert HTML comments?

Yes. HTML comments like <!-- comment --> are converted to JSX comments {/* comment */}.
