HTML to JSX Converter

This developer-friendly utility seamlessly bridges the gap between traditional HTML mockups and modern Javascript frameworks. It allows you to rapidly transpile standard HTML or SVG tags into completely compliant React syntax (JSX) instantly in your browser.

We prioritize your project's security. This application runs entirely on your local machine using "Client-Side Processing". Consequently, pasting proprietary company templates or unreleased UI designs poses zero risk, as no code is ever uploaded to our servers.

1. Paste Output: Drop any snippet of regular HTML code directly into the left "Input" text area.
2. Instant Evaluation: The system captures your syntax as you type and simultaneously translates it into valid JSX on the right.
3. Copy and Use: Verify the result formatting, hit the "Copy" module button, and paste directly into your `.js`, `.jsx`, or `.tsx` React framework files.

Main Conversion Rules applied

• class=" " attributes map naturally to className=" ".
• for=" " attributes transform to HTML-DOM property htmlFor=" ".
• Self-closing void elements like <br>, <hr>, <img>, and <input> automatically receive their trailing slash /> to prevent strict React compile errors.
• Text-string Inline Styles (e.g., style="font-size: 10px;") are deeply parsed and converted into camel-cased JS objects style={{fontSize: '10px'}}.
• Common event listeners (like onclick) are transformed into React's camelCased synthetic events (like onClick).

JSX (JavaScript XML)

A JavaScript syntax extension used in React and Next.js. It lets you write UI components in an HTML-like notation, but attribute names differ from HTML — for example, class becomes className.

className

The JSX attribute used instead of HTML's class. The rename avoids a collision with JavaScript's reserved word class.

htmlFor

The JSX counterpart to HTML's for attribute on <label> elements. It is renamed to prevent a conflict with JavaScript's for loop keyword.

Self-Closing Tags

In JSX, void elements such as <img>, <br>, and <input> must be explicitly closed with a trailing slash: <img />. Optional in HTML but mandatory in JSX.

Inline Styles

In JSX, the style attribute must receive a JavaScript object, not a CSS string. Property names are camelCased: style={{color: "red", fontSize: "16px"}}.

React Component

A reusable function or class that returns JSX. Components are the building blocks of a React application, each responsible for rendering a specific piece of the UI.

AST (Abstract Syntax Tree)

A tree-structured representation of your source code's syntax. This converter parses HTML into an AST and then regenerates it according to JSX rules to produce valid output.

Q.Is my code sent to your servers?

No. All HTML-to-JSX conversion runs entirely inside your browser's JavaScript engine. The code you paste is never transmitted to any external server.

Q.What conversions does it apply automatically?

class→className, for→htmlFor, inline style strings→object notation, self-closing void tags, and preservation of data-* attributes — all aligned with React's JSX specification.

Q.Can I use the output as TypeScript (TSX)?

Yes, the JSX output is generally valid TSX as well. Type annotations and TypeScript-specific syntax must be added manually afterward.

Q.Can it handle complex HTML like tables and forms?

Yes, complex structures including tables, forms, and SVG are supported. Note that template language syntax (EJS, Pug, etc.) should be pre-rendered to plain HTML before pasting.

Q.How do I copy the result?

Click the "Copy" button above the JSX output panel. The converted code is placed directly onto your clipboard, ready to paste into your .jsx or .tsx file.

Q.Are SVG attributes also converted?

Yes. SVG-specific attributes such as stroke-width and fill-opacity are automatically camelCased (e.g., strokeWidth, fillOpacity) to comply with React's JSX naming rules.

Q.Does it work on smartphones?

Yes. The interface is fully responsive. You can paste HTML, view the JSX output, and copy the result from any modern mobile browser.

• Importing Designer Mockups: Rapidly transform pure HTML blocks delivered by Web Designers into reusable React functional components.
• Migrating Legacy Projects: During transitions from jQuery architectures to Vue/React modern frameworks, quickly restructure the foundational DOM structural code.
• Copying from UI Kits: Directly transpose standard responsive blocks from sites like pure Bootstrap or unmodified Tailwind components into your Next.js application effortlessly.
