Frequently Asked Questions

What is the difference between HTML and JSX?

JSX (JavaScript XML) is a syntax extension used in React that looks similar to HTML but has some key differences. In JSX, you use className instead of class, htmlFor instead of for, and inline styles must be JavaScript objects rather than strings. JSX also requires all tags to be properly closed.

Does this tool support all HTML attributes?

Yes, the converter handles all standard HTML attributes and converts them to their JSX equivalents. This includes event handlers (onclick → onClick), aria attributes, data attributes, and custom attributes.

Can I convert HTML with embedded JavaScript?

The converter focuses on HTML-to-JSX transformation. For HTML with embedded scripts, you may need to manually handle the JavaScript portions after conversion.

Is my code safe when using this tool?

Absolutely. All conversion happens entirely in your browser. No code is sent to any server, making it completely private and secure for sensitive codebases.
