About HTML to JSX Converter Tool

This free online HTML to JSX converter transforms standard HTML into valid React JSX syntax and vice versa. It handles all the common conversions that trip up React developers: class to className, for to htmlFor, inline style strings to JavaScript objects, self-closing tags (img, br, input, hr), HTML comments to JSX comments, and 20+ attribute name mappings. Perfect for migrating HTML templates to React components.

Why Convert HTML to JSX?

React uses JSX instead of raw HTML, and the differences cause frequent errors: "class" is a reserved word in JavaScript (use "className"), "for" conflicts with loops (use "htmlFor"), style attributes must be objects with camelCase properties instead of strings, void elements need self-closing slashes, and HTML comments use a different syntax. Manually fixing these across a large HTML template is tedious and error-prone. This converter handles all transformations instantly.

Key Benefits

  • Attribute mapping: class → className, for → htmlFor, tabindex → tabIndex, and 20+ more
  • Style conversion: Inline style strings become JSX style objects with camelCase properties
  • Self-closing tags: img, br, input, hr, meta, link get proper JSX self-closing syntax
  • Comment conversion: HTML comments become JSX comments and back
  • Bidirectional: Convert HTML to JSX and JSX back to HTML
  • Completely private: Your HTML/JSX code never leaves your browser
