About the HTML to JSX Tool
Pasting HTML directly into a React component does not work. JSX looks like HTML but is really JavaScript, so reserved words collide: class becomes className, for becomes htmlFor, style takes an object rather than a string, and every void element must be explicitly self-closed.
Fixing those by hand across a large block of markup is slow and easy to get wrong. This converter applies all the transformations automatically, producing JSX that compiles cleanly. It runs in your browser with no upload, so proprietary markup stays local.
How to Use HTML to JSX
- Paste your HTML markup into the input area.
- Press Convert to apply the JSX transformations.
- Review the output, particularly any inline style conversions.
- Paste the JSX into your React component.
When to Use This Tool
- Porting a static HTML template into React components
- Converting a purchased HTML theme for use in a React application
- Migrating legacy markup during a framework rewrite
- Adapting HTML email templates for a React-based builder
- Reusing markup from a design handoff inside a component
Things Worth Knowing
- class becomes className and for becomes htmlFor, since both are reserved words in JavaScript.
- Inline style strings are converted to JavaScript objects with camelCased property names.
- Void elements such as
,
, and are self-closed, which JSX requires.

Frequently Asked Questions
Why does JSX use className instead of class?
JSX compiles to JavaScript, where class is a reserved keyword. React chose className to match the DOM property name that already existed in JavaScript.
How are inline styles handled?
A style string becomes a JavaScript object with camelCased keys, so style="font-size:14px" becomes style={{fontSize:'14px'}}. Note the double braces — one for JSX interpolation, one for the object literal.
Are HTML comments converted?
They become JSX comment expressions wrapped in braces, since HTML comment syntax is not valid inside JSX.
Will the output work in Vue or Svelte?
No. This targets React’s JSX specifically. Vue and Svelte use their own template syntaxes with different attribute conventions.
