Converting HTML to JSX is a common task when migrating static HTML templates to React projects or when integrating third-party HTML snippets into JSX-based frameworks like Next.js, Gatsby, or Create React App.
This free online HTML to JSX converter handles the mechanical transformation automatically: it converts class attributes to className, for attributes to htmlFor, and transforms kebab-case attributes to their camelCase equivalents. It also self-closes void elements (img, input, br, hr) and properly handles boolean attributes like disabled, checked, and required.
All processing happens client-side — your HTML never leaves your browser. Use the wrap-in-fragment option for multi-root HTML structures, or disable it for single-root templates you want to control manually. Combined with our other developer tools like the code formatter and HTML playground, it is part of a complete toolkit for React developers.
Frequently Asked Questions
Q:How does the HTML to JSX converter work?
It uses regex-based string transformation to convert standard HTML into React-compatible JSX syntax. It handles className (from class), htmlFor (from for), camelCase attribute conversion (e.g., tabindex → tabIndex, autocomplete → autoComplete), boolean attributes (disabled, checked, required), self-closing tags for void elements like img and input, and SVG attribute preservation.
Q:Does this handle all edge cases?
It handles the most common HTML to JSX conversions, including class names, labels, form attributes, boolean attributes, kebab-case to camelCase conversion, and self-closing tags. For complex cases with inline event handlers (onclick → onClick), dynamic JavaScript expressions, or dangerouslySetInnerHTML, you may need manual adjustments.
Q:Can I convert SVG code to JSX?
Yes — SVG attributes like viewBox, strokeWidth, fillOpacity, and strokeDasharray are preserved correctly. The converter recognizes SVG-specific attributes and keeps them in their original form while still converting standard HTML attributes within the SVG.
Q:Do I need to wrap the output in a fragment?
The converter offers an option to wrap output in a React fragment (<>...</>). Enable this when converting HTML that has multiple root elements (like a list of items) to avoid adding unnecessary wrapper divs. Disable it when you want to control the structure yourself.
Q:Is this safe for converting production code?
The conversion is deterministic and runs entirely in your browser. While it handles almost all standard HTML patterns, always review the output for correctness, especially for complex nested structures, inline event handlers, and dynamic expressions that may need custom JSX syntax.
