HTML to JSX Converter — Convert HTML for React

Copying HTML into a React component always requires manual cleanup — class becomes className, for becomes htmlFor, onclick becomes onClick, and void elements need self-closing tags. HTML to JSX Converter handles all of that automatically, showing a transformation count so you know exactly what changed.

What is HTML to JSX Conversion?

JSX is React's HTML-like syntax, but it's not HTML. JSX uses JavaScript attribute names, camelCase event handlers, and strict XML rules for void elements. Converting HTML to JSX by hand is tedious and error-prone. HTML to JSX Converter automates every transformation so the output is valid JSX the moment you paste.

What Gets Transformed?

  • class → className (all occurrences)
  • for → htmlFor (on label elements)
  • tabindex → tabIndex
  • onclick → onClick, onchange → onChange, onsubmit → onSubmit, and all other HTML event attributes
  • Void elements (br, img, input, hr, meta, link) → self-closed with />
  • Style attribute values left in place — manual conversion to object syntax is noted

Why Use HTML to JSX Converter?

Frontend developers frequently copy HTML from static sites, design handoffs, documentation, or UI libraries and need to drop it into React components. The converter eliminates all manual renaming and turns a multi-minute task into an instant paste-and-go.

How to Use HTML to JSX

  1. Paste your HTML markup into the left panel
  2. The JSX output appears in the right panel instantly
  3. A transformation count shows how many attributes and elements were changed
  4. Click Copy to copy the JSX to clipboard
  5. Paste directly into your React component

Example Use Case

You're implementing a design from a Figma handoff that provided HTML. The snippet has class attributes, onclick handlers, and self-closing img tags without the slash. Paste into HTML to JSX Converter — all class attributes become className, onclick becomes onClick, and img tags are self-closed. The output is paste-ready JSX.

Tips

  • Paste full component trees, not just individual tags — the converter handles nested structures
  • style='...' inline styles are passed through — you'll still need to manually convert them to object syntax ({ style={{ color: 'red' }} })
  • Check the transformation count — a count of 0 means the HTML may already be valid JSX
  • Works well for Bootstrap, Tailwind, or any plain HTML snippets destined for React

Frequently Asked Questions

Yes, completely free with no signup required.

No. All conversion runs in your browser. Nothing is sent to a server.

Inline style strings are preserved as-is. JSX requires style to be a JavaScript object ({ color: 'red' }) rather than a string — that conversion still needs to be done manually.

Standard HTML attributes are transformed. Custom data-* attributes are passed through unchanged since they're valid in JSX.

Common SVG attributes like viewBox and xmlns are passed through. Full SVG-to-JSX conversion with fill/stroke → className mapping is not currently supported.
