How to use
- Paste an HTML fragment, open a UTF-8 file or load Sample.
- Choose indentation and select Convert to JSX.
- Review the generated markup, then copy or download it.
Moving HTML markup into React
HTML copied from a template often needs changes before it can be placed in JSX. Common differences include className, htmlFor, self-closing elements and the shape of inline styles.
The converter handles markup structure. Component state, event callbacks and application logic still need to be written where the generated JSX is used.
Attribute and style conversion
HTML attributes are mapped to their React forms, including className and htmlFor. Common SVG names are handled with React attribute casing.
Inline CSS becomes a style object, and the result is formatted as JSX. Literal text is escaped as needed rather than treated as JavaScript expressions.
<label class="field" for="email">Email<input id="email"></label><label className="field" htmlFor="email">Email<input id="email" /></label>Abbreviated attribute-conversion example. The full output is formatted and includes a fragment wrapper.
Structure and behavior
The HTML fragment is parsed before conversion. The output uses a fragment wrapper and self-closing syntax where appropriate.
Script elements and inline event attributes are removed. This does not convert their behavior into React callbacks or make every remaining URL and style suitable for your application.
Integrating the result
Copy the JSX into a component render or return expression. Reconnect behavior manually and review inline styles, especially repeated fallback declarations or !important rules that a style object cannot represent fully.
Text input up to 1 MiB. CSS and HTML transformations run in a worker with a 30-second limit. Color tools use sRGB; generated styles are previews and require testing in your own layout.
Frequently asked questions
Does this create a complete React component?
No. It produces JSX markup. Add the surrounding component, imports, data and behavior in your project.
What happens to scripts and onclick attributes?
Script elements and inline event attributes are removed. Their code is not executed or translated into React event handlers.
Why are braces in my text still shown as text?
The input is parsed as HTML. Literal braces are escaped for JSX rather than treated as an expression to evaluate.
Are inline styles converted exactly?
Common declarations become React style properties. Repeated fallback declarations and !important cannot always be represented faithfully by a JavaScript style object.
Can I convert SVG markup?
Common SVG attributes are mapped to React names. Test the output in your component, including IDs, references and any application-specific attributes.
