HTML to JSX Converter

Paste plain HTML and get React-ready JSX back — className, htmlFor, camelCased attributes, self-closing tags and inline style objects all handled, so the snippet drops straight into a component.

What is an HTML to JSX converter?

JSX looks almost identical to HTML, but React reads it as JavaScript — and that one difference breaks a handful of attributes that are perfectly valid in HTML. class collides with the JavaScript reserved word, for clashes with the loop keyword, inline style is a string in HTML but an object in JSX, and void elements like <img> must be explicitly self-closed. An HTML to JSX converter rewrites all of that for you so a snippet of markup becomes a snippet you can paste into a React component.

This tool walks your markup and applies the React rules: class becomes className, for becomes htmlFor, inline style="…" strings are parsed into {{ camelCasedProperty: 'value' }} objects, onclick-style handlers are camelCased into onClick, and tags are closed where JSX demands it. The result is indented so it reads cleanly when you drop it into a return ( … ).

Conversion happens entirely in your browser — paste freely, even from internal templates or design files, because nothing is uploaded.

How to convert HTML to JSX

  1. 1

    Paste your HTML

    Drop an HTML snippet or full block of markup into the input pane, or load the sample to see it in action.

  2. 2

    Get JSX instantly

    Conversion runs live, so the React-ready JSX appears in the output pane as you type.

  3. 3

    Drop it into a component

    Copy the result and paste it inside a component's return statement — the attributes are already React-safe.

  4. 4

    Review the edge cases

    Scan for spots that need manual attention, such as JS-heavy event handlers or multiple root elements that should be wrapped in a fragment.

Why it saves React developers time

No more className typos

Every class and for attribute is rewritten correctly, so you stop hitting the silent bug where class is ignored in React.

Inline styles done right

String styles become valid JSX objects with camelCased keys, instead of throwing 'style must be an object' at runtime.

Paste designer or CMS markup

Convert HTML straight out of a template, email or CMS into JSX without hand-editing dozens of attributes.

Local and private

Markup is transformed in-browser, so proprietary templates and unreleased UI never leave your machine.

Example: HTML in, JSX out

A typical chunk of HTML on the left, converted to React-ready JSX on the right.

HTML → JSX
<div class="card">
  <label for="email">Email</label>
  <input type="email" id="email">
  <p style="color: red; font-size: 14px">Required</p>
</div>
<div className="card">
  <label htmlFor="email">Email</label>
  <input type="email" id="email" />
  <p style={{ color: 'red', fontSize: '14px' }}>Required</p>
</div>

The real gotchas when converting HTML to JSX

  • class → className: class is a reserved word in JavaScript, so React uses className. Forget this and your styles silently don't apply.
  • for → htmlFor: a <label for="email"> must become htmlFor="email" in JSX for the same reason.
  • Inline styles are objects: style="color: red" becomes style={{ color: 'red' }}, and hyphenated properties get camelCased — background-color → backgroundColor.
  • camelCased attributes: tabindex, maxlength and readonly become tabIndex, maxLength and readOnly.
  • Self-closing void tags: <br>, <img> and <input> have no closing tag in HTML but must be closed in JSX as <br />.
  • One root element: JSX returns a single node, so sibling elements need a wrapping <div> or a fragment <>…</>.

What you may still need to do by hand

A converter handles the mechanical, attribute-level translation, but it can't read your intent. Event handlers that contained real JavaScript — onclick="doThing(); track()" — become JSX expressions, yet you'll usually want to replace them with a proper React handler function and component state. Comments (<!-- … -->) need converting to {/* … */}, and any markup with multiple top-level elements should be wrapped in a fragment. Treat the output as a fast first pass that removes the tedious 90%, then wire up behaviour the React way.

Frequently asked questions

JSX is compiled to JavaScript, so attributes that collide with JS keywords or expect a different type have to change: class becomes className, for becomes htmlFor, inline styles become objects, and void tags must be self-closed. The converter applies all of these so the markup is valid in a React component.

It parses the style string into a JSX object. Each declaration becomes a key/value pair, hyphenated CSS properties are camelCased (background-color → backgroundColor) and values are quoted, producing style={{ … }} that React accepts.

Yes. Void elements like <img>, <br> and <input> have no closing tag in HTML, but JSX requires every element to be closed, so they're emitted in self-closing form such as <img ... />.

Attribute names are camelCased — onclick becomes onClick — and the value is wrapped as a JSX expression. For anything beyond a trivial call you'll still want to replace it with a real React handler function rather than inline code.

No. The conversion runs entirely in your browser, so private templates, CMS exports and unreleased markup never touch a server.

For static markup, usually yes — paste it inside a return statement. Anything with real interactivity (event logic, dynamic values) or multiple root elements needs a quick manual pass to add a fragment, state or proper handlers. Treat it as a strong first draft.
