HTML to JSX Converter

Convert HTML to valid JSX for React: class to className, inline styles to objects, self-closed void tags and camelCased attributes — instantly, in your browser.

What is the HTML to JSX Converter?

The ByteTools HTML to JSX Converter rewrites plain HTML as JSX you can paste straight into a React component.

  • class → className, for → htmlFor, and 30+ attribute renames
  • Inline style strings become JSX style objects with camelCased properties
  • Void elements (<br>, <img>, <input>) are self-closed
  • HTML comments become {/* */} and reserved braces in text are escaped
  • Keeps data-*, aria-* and SVG attributes intact
  • 100% client-side conversion with one-click copy

About the HTML to JSX Converter

The ByteTools HTML to JSX Converter rewrites plain HTML as JSX you can paste straight into a React component. It renames class to className and for to htmlFor, camelCases attributes like tabindex and stroke-width, converts inline style strings into JavaScript style objects, self-closes void elements like <br> and <img>, and turns HTML comments into {/* JSX comments */}.

It parses your markup with the browser's own HTML parser rather than fragile find-and-replace, so nested elements, SVG attributes, data-* and aria-* attributes and boolean attributes such as disabled all come out correctly. Multiple top-level elements are wrapped in a fragment automatically.

The conversion runs entirely in your browser — nothing you paste is uploaded — and the output is ready to copy with one click.

Frequently asked questions

Why does React use className instead of class?

JSX compiles to JavaScript, where class is a reserved keyword, so React exposes the attribute as className. The same applies to for, which becomes htmlFor because for is also reserved.

How are inline styles converted?

An HTML style string like style="margin-top: 10px; color: red" becomes a JavaScript object: style={{ marginTop: "10px", color: "red" }}. Property names are camelCased, values become strings, and CSS custom properties (--var) keep their original quoted names.

What happens to HTML comments?

JSX has no <!-- --> syntax, so comments are converted to the JSX form {/* comment */}, which survives inside element children.

Does the converter handle SVG markup?

Yes. SVG attributes like stroke-width and fill-rule are camelCased to strokeWidth and fillRule, xlink:href becomes xlinkHref, and case-sensitive tags such as linearGradient are preserved, matching what React expects.

Why are curly braces in my text escaped?

In JSX, { starts a JavaScript expression, so literal braces in text would break compilation. The converter wraps them as {'{'} and {'}'} so your text renders exactly as written.

Can I convert a whole HTML page?

You can paste a full document, and the converter will transform the body content. In practice JSX components represent fragments of a page, so converting sections at a time usually gives more useful output than converting <html> and <head> wrappers.
