What does an HTML to JSX converter do?

It transforms standard HTML markup into valid React JSX syntax. Key changes include renaming class to className, for to htmlFor, converting inline style strings to JavaScript objects, self-closing void elements like and , and converting HTML event handlers like onclick to camelCase React equivalents like onClick.

Why does React use className instead of class?

Because JSX compiles to JavaScript, and class is a reserved keyword in JavaScript. To avoid conflicts, React uses className for the CSS class attribute. Similarly, for becomes htmlFor because for is also a reserved word in JavaScript (used in for loops).

Does this tool convert inline styles correctly?

Yes. HTML inline styles like style="color: red; font-size: 16px" are converted to JSX object syntax: style={{ color: 'red', fontSize: '16px' }}. CSS property names are automatically camelCased — font-size becomes fontSize, background-color becomes backgroundColor, and so on.

Can I use the converted JSX directly in my React component?

In most cases yes, but there may be edge cases to review — especially complex nested structures, custom data attributes, or SVG elements. Always test the output in your actual component. The converter handles the most common HTML patterns correctly.

Is my HTML code sent to any server?

No. All conversion happens entirely in your browser using JavaScript. Your HTML code never leaves your device, ensuring complete privacy.
