readonly → readOnly
Inline CSS → JSX style objects
Self-closing HTML elements
React-compatible SVG attributes
Multiple root elements
JSX formatting

The workflow is simple:

Paste HTML → Convert to JSX → Copy JSX

How to Convert HTML to JSX

Paste your HTML into the HTML Input editor.
Click Convert to JSX.
Review the generated JSX.
Check any conversion notes or warnings.
Click Copy JSX and paste it into your React project.

You can also load sample code to see how the converter works.

HTML to JSX Example

HTML

[object HTMLPreElement]

JSX

[object HTMLPreElement]

The converter saves you from manually fixing these React-specific syntax differences.

Convert `class` to `className`

HTML uses:

[object HTMLPreElement]

JSX uses:

[object HTMLPreElement]

The converter changes the actual HTML attribute safely instead of blindly replacing every occurrence of the word class.

Convert Inline Styles to JSX

HTML inline styles use a CSS string:

[object HTMLPreElement]

JSX uses a JavaScript object:

[object HTMLPreElement]

With inline-style conversion enabled, CSS properties such as background-color are converted to React-friendly camelCase names such as backgroundColor.

Fix Self-Closing Tags

HTML often allows:

[object HTMLPreElement]

JSX requires:

[object HTMLPreElement]

The tool automatically fixes common empty elements for JSX.

Convert SVG to JSX

SVG markup often contains attributes that need React-compatible names.

For example:

[object HTMLPreElement]

becomes:

[object HTMLPreElement]

This makes the converter useful for SVG icons, illustrations, and code exported from design tools.

Convert HTML to a React Component

Enable React Component Mode if you want the converted markup wrapped inside a reusable function component.

Input:

[object HTMLPreElement]

Output:

[object HTMLPreElement]

You can also choose your own component name.

Useful for React and Next.js Developers

This HTML to JSX converter is useful when working with:

Static HTML websites
Bootstrap templates
Landing pages
Legacy front-end projects
React components
Next.js projects
SVG markup
UI templates
Design-tool exports

Instead of manually correcting dozens of attributes, you can convert the markup first and then focus on props, state, components, and application logic.

Helpful Conversion Feedback

Some HTML cannot be converted perfectly without understanding the JavaScript around it.

For example, inline HTML event handlers may need manual review.

If the tool detects potentially incomplete or unusual markup, it provides a warning rather than silently returning an empty result.

This is especially helpful when working with copied templates or older HTML.

Why Use an HTML to JSX Converter?

Manual conversion becomes repetitive when working with large HTML snippets.

This tool helps reduce work such as:

Replacing HTML attributes
Fixing self-closing tags
Converting inline styles
Updating SVG properties
Formatting nested markup
Wrapping multiple root elements
Preparing React components

That makes it useful for both experienced React developers and beginners learning JSX.
