HTML to JSX Converter

Convert HTML to JSX for React online. Transforms class to className, style strings to objects, self-closing tags, and more. Free and instant.

About HTML to JSX Conversion

JSX is React's syntax extension that looks like HTML but has important differences. When migrating HTML templates to React components, you need to convert class to className, for to htmlFor, inline style strings to JavaScript objects, and ensure all tags are properly closed. Event handlers also need conversion from lowercase (onclick) to camelCase (onClick). This tool automates all of these transformations. Paste any HTML snippet and get valid JSX output instantly. It handles self-closing void elements (br, hr, img, input), converts HTML comments to JSX comments, and transforms common HTML attributes to their JSX equivalents. Perfect for migrating static HTML sites to React or converting HTML templates from design tools.

Frequently Asked Questions

What does HTML to JSX conversion change?
The main changes are: class โ†’ className, for โ†’ htmlFor, inline style strings โ†’ style objects, self-closing tags get />, HTML comments โ†’ {/* */}, and event handlers become camelCase.
Why can't I use class in JSX?
In JSX, 'class' is a reserved JavaScript keyword. React uses 'className' instead. Similarly, 'for' becomes 'htmlFor' because 'for' is also a JS reserved word.
How are inline styles converted?
CSS style strings like style="color: red; font-size: 16px" are converted to style objects: style={{color: "red", fontSize: "16px"}}. CSS properties become camelCase.
Does it handle self-closing tags?
Yes. HTML void elements like <br>, <hr>, <img>, and <input> are converted to self-closing JSX: <br />, <hr />, <img />, <input />.
