HTML to JSX Converter - Paste HTML, Get React Code

How the HTML to JSX Converter Works

1. 01Paste your HTML into the left pane, or load the sample to see the conversion rules in action.
2. 02The markup is parsed with the browser's real HTML parser (DOMParser), not regex substitution.
3. 03Each element is rebuilt as JSX: attributes renamed, styles converted to objects, void tags self-closed, comments wrapped.
4. 04Copy the JSX from the right pane straight into your React component.

Converting HTML Snippets Into React Components

Paste any fragment: a full page body, a single card, or an SVG icon. Because the converter uses DOMParser, it tolerates the messy HTML you find in the wild - unquoted attributes, unclosed tags, and inconsistent casing all normalize correctly before conversion. The output follows React's rules exactly: class becomes className, for becomes htmlFor, tabindex becomes tabIndex, and the rest of the attribute map covers form attributes (maxlength, readonly, autocomplete), table attributes (colspan, cellpadding), media attributes (autoplay, playsinline), event handlers (onclick to onClick), and SVG names such as viewBox and preserveAspectRatio. Inline style strings turn into style objects with camelCased properties, including vendor prefixes (-webkit-transform becomes WebkitTransform) and CSS custom properties, which stay quoted. Multiple top-level elements are wrapped in a fragment so the result is always a valid return value. After pasting into your component, replace static attribute values with props or state where needed, and convert onClick string handlers into real function references - the converter preserves them as attribute text since it cannot invent your handler logic.

When to Use the HTML to JSX Converter

Use it whenever HTML needs to live inside a React component: porting a static site or landing page to Next.js, adapting a Bootstrap or Tailwind template, embedding an SVG exported from Figma or Illustrator, or copying a snippet from documentation that was written for plain HTML. It is also a teaching aid - the side-by-side view makes JSX's differences from HTML concrete for developers learning React.

Common Use Cases

• —Porting static HTML pages or templates into React and Next.js components
• —Converting SVG icons exported from design tools into inline JSX
• —Adapting HTML email markup or CMS output for a React front end
• —Learning how JSX differs from HTML with instant side-by-side feedback
• —Cleaning up markup before formatting props as JSON JSON Formatter & Validator - Instant Results

Expert Tips

• ✻After converting, extract repeated blocks into components and replace hardcoded text with props - the converter gives you valid JSX, but componentization is still your job.
• ✻For big SVGs, consider running the output through an optimizer first; fewer path nodes means less JSX to maintain.
• ✻Boolean attributes like disabled and checked convert to bare props; remember that in React, checked needs an onChange handler or defaultChecked instead.

Frequently Asked Questions

Why does class become className?→

JSX compiles to JavaScript, where class is a reserved keyword. React therefore uses className for the class attribute, and htmlFor for the label attribute for. The converter applies these and over 100 other renames automatically.

How are inline styles handled?→

A style string like style="background-color: red; margin-top: 8px" becomes a JavaScript object: style={{ backgroundColor: "red", marginTop: "8px" }}. Vendor-prefixed properties and CSS custom properties are converted correctly too.

Are data- and aria- attributes changed?→

No. React expects data-* and aria-* attributes in their original hyphenated form, so the converter passes them through unchanged.

What happens to HTML comments?→

They are preserved as JSX comment expressions ({/* ... */}) instead of being dropped, so documentation embedded in the markup survives the conversion.
