HTML to JSX Converter
LiveConvert HTML markup to valid React JSX — class→className, style strings→objects, and more.
Understanding React JSX Syntax
JSX (JavaScript XML) is React's syntax extension that allows writing HTML-like code in JavaScript components. However, JSX differs from HTML in important ways: class becomes className, for becomes htmlFor, style accepts objects rather than strings, self-closing tags are required, event handlers use camelCase (onClick vs onclick), and boolean attributes work differently. Converting HTML templates, snippets, and designs to valid JSX is a constant task when building React applications from HTML prototypes, email templates, or design tool exports.
Transform HTML code into valid React JSX syntax automatically. Converts class to className, for to htmlFor, inline styles to objects, self-closes void elements, and handles all HTML-to-JSX attribute differences. Essential for React developers.
The Devkitr HTML to JSX Converter transforms standard HTML into valid React JSX by applying all necessary syntax changes. Paste HTML to get JSX with className, camelCase event handlers, style objects, self-closing tags, and other JSX-required transformations — ready to use in React components.
In a typical development workflow, HTML to JSX Converter becomes valuable whenever you need to convert html markup to valid react jsx. Whether you are working on a personal side project, maintaining production applications for a company, or collaborating with a distributed team across time zones, having a reliable browser-based conversion tool eliminates the need to install desktop software, write one-off scripts, or send data to third-party services that may log or retain your information. Since HTML to JSX Converter processes everything locally on your device, your data stays private and your workflow stays uninterrupted — open a browser tab, paste your input, get your result.
Key Features
Attribute Conversion
Converts class to className, for to htmlFor, tabindex to tabIndex, and all other HTML-to-JSX attribute name changes.
Style Object Transform
Converts inline style strings (style="color: red; font-size: 14px") to JSX style objects (style={{ color: "red", fontSize: "14px" }}).
Self-Closing Tag Fix
Adds self-closing syntax to void elements (<img>, <br>, <input>, <hr>) that JSX requires but HTML allows to leave open.
Event Handler Conversion
Transforms lowercase HTML event attributes (onclick, onchange) to camelCase JSX handlers (onClick, onChange).
How to Use HTML to JSX Converter
Paste HTML Code
Enter HTML from design tools, templates, codepen prototypes, or any HTML source you need to convert to JSX.
Review JSX Output
Check the converted JSX for correct attribute names (className), style objects, and self-closing elements.
Handle Special Cases
Review comments (<!-- --> → {/* */}), innerHTML usage, and SVG attributes that may need manual attention.
Copy JSX Component
Copy the valid JSX into your React component files, wrapping in a parent element or fragment if needed.
Use Cases
React Component Prototyping
Convert HTML/CSS prototypes from design tools (Figma HTML export, Webflow) to React JSX components.
Email Template to React
Convert HTML email templates to React Email or MJML-React JSX components for programmatic email generation.
Migrating from Static HTML to React
Convert static HTML pages to React components during migration from server-rendered or static sites to React SPAs.
Third-Party HTML Widget Integration
Convert HTML embed codes and widget snippets to JSX for rendering in React applications via dangerouslySetInnerHTML or component conversion.
Pro Tips
After conversion, wrap multiple sibling elements in a React Fragment (<>...</>) — JSX requires a single root element.
Inline style conversion produces JavaScript objects — numbers without units default to pixels in React (fontSize: 14 becomes 14px).
SVG attributes in JSX use camelCase (viewBox, fillOpacity, strokeWidth) — the converter handles common ones but check SVG-heavy content.
Comments change from HTML (<!-- -->) to JSX ({/* */}) — ensure converted comments do not break the component render.
Common Pitfalls
Using the HTML class attribute in JSX without converting to className
Fix: JSX uses className for CSS classes because "class" is a reserved JavaScript keyword. The converter handles this, but verify after manual edits.
Leaving unclosed HTML tags that JSX requires to be self-closed
Fix: HTML allows <img>, <br>, <input> without closing. JSX requires <img />, <br />, <input />. The converter fixes these automatically.
Pasting converted JSX with inline event handlers that reference global functions
Fix: HTML onclick="handleClick()" becomes onClick={handleClick} in JSX — the function must be defined in or imported by the React component.
Frequently Asked Questions
QWhat attributes are converted?
class→className, for→htmlFor, tabindex→tabIndex, onclick→onClick, and all other HTML/JSX attribute differences.
QHow are inline styles handled?
Inline style strings like style="color: red" are converted to JSX objects: style={{ color: "red" }}.
QDoes it handle self-closing tags?
Yes. Tags like <br>, <img>, and <input> are converted to self-closing JSX format: <br />, <img />, <input />.
QDoes it wrap in a fragment?
If the HTML has multiple root elements, they are automatically wrapped in a React fragment (<>...</>).
