What is HTML to JSX Conversion?
JSX is the syntax extension used by React that looks like HTML but has important differences. When migrating HTML templates to React components, you need to transform attributes and syntax to be JSX-compatible. This tool automates the tedious parts of that process. It converts class to className, for to htmlFor, inline style strings to JavaScript objects with camelCase properties, and self-closes void elements like img, br, and hr. It also handles event handlers, boolean attributes, HTML comments, and over 60 SVG-specific attribute name conversions.
How to Use This Tool
Paste your HTML code into the input area. The tool converts it to valid JSX in real time as you type. Use the "Load sample" button to see a comprehensive example that demonstrates class, style, for, void element, event handler, and comment conversions. The output panel shows the converted JSX, and conversion badges below indicate which transformations were applied. Copy the result with one click and paste it directly into your React component.
Common Use Cases
- Migrating existing HTML templates to React or Next.js components
- Converting HTML snippets from design tools, CMS editors, or documentation into JSX
- Quickly fixing JSX syntax errors caused by HTML-style attributes
- Converting SVG markup to JSX-compatible syntax for inline use in React
Why Use a Client-Side Tool?
All conversion happens entirely in your browser. Your HTML code is never sent to any server, which matters when working with proprietary templates or code that contains sensitive information. The tool processes input instantly with no network latency, and it works fully offline. It is a reliable utility to keep in your development workflow for any time you need to move HTML into a React project.
Frequently Asked Questions
What HTML attributes does this tool convert?
The converter handles over 60 attribute mappings including class to className, for to htmlFor, tabindex to tabIndex, readonly to readOnly, and SVG-specific attributes like stroke-width to strokeWidth and clip-path to clipPath.
How are inline styles converted?
HTML inline styles like style="color: red; font-size: 24px" become JSX style objects: style={{ color: "red", fontSize: "24px" }}. CSS properties with hyphens are converted to camelCase automatically.
Does this tool handle self-closing tags?
Yes. Void elements such as img, br, hr, input, link, and meta are automatically self-closed with a trailing slash as JSX requires. For example, <img src="photo.jpg"> becomes <img src="photo.jpg" />.
