HTML to React JSX & TSX Component Converter

Universal browser-native HTML to React 19 JSX & TypeScript TSX converter. Converts HTML attributes, inline styles to style objects, self-closing void tags, SVG attributes, and generates TypeScript interface components.

Automatic attribute transformation: class -> className, for -> htmlFor, tabindex -> tabIndex, and event handlers
Inline CSS parser: Converts string style="..." declarations into typed React style={{ ... }} JavaScript objects
Self-closing tag correction: Automatically closes void HTML5 elements (<img />, <input />, <br />, <hr />)
SVG attribute conversion: Converts kebab-case SVG attributes (stroke-width, fill-rule, clip-path) to camelCase
TypeScript generation: Generates typed React.FC<Props> functional components with customizable component names

The Engineering Guide to Converting HTML to Modern React JSX & TSX

In-depth specifications, architectural mechanics, real-world code implementations, and industry best practices.

01

Why HTML Markup Cannot Be Directly Pasted into React

JSX is not HTML; it is an XML-like syntax extension for ECMAScript (JavaScript). Because JSX transpiles directly into React.createElement() or the modern JSX runtime jsx() function calls, attribute names must conform to valid JavaScript identifiers. Reserved keywords like "class" and "for" clash with JavaScript class declarations and for-loops, necessitating "className" and "htmlFor". Furthermore, JSX enforces strict XML syntax rules: all tags must be explicitly closed, and inline styles must be passed as JavaScript objects rather than raw CSS semicolon strings.

02

Inline Style String to JavaScript Object Parsing

In standard HTML, styles are defined as a single semicolon-delimited string (e.g. style="margin-top: 12px; font-weight: bold; background-color: #0f172a;"). In React, the style attribute accepts a JavaScript dictionary where CSS property names are converted from kebab-case to camelCase (e.g. style={{ marginTop: 12, fontWeight: "bold", backgroundColor: "#0f172a" }}). Our converter parses each declaration, handles CSS custom properties (--var), and transforms vendor prefixes (-webkit-, -moz-) into camelCase identifiers.

03

Handling SVG Attributes in React 19

SVG markup pasted from Figma, Illustrator, or icon sets contains dozens of hyphenated attributes such as stroke-width, stroke-linecap, stroke-linejoin, fill-opacity, and clip-rule. While React 16+ supports arbitrary DOM attributes, React tooling, Linters (ESLint), and TypeScript enforce camelCase properties (strokeWidth, strokeLinecap, fillRule) to prevent runtime warnings and ensure strict type-safety.

04

Void Tags and XML Self-Closing Syntax

HTML5 permits unclosed void elements like <img src="...">, <input type="text">, <br>, and <hr>. In JSX, unclosed void tags trigger severe syntax compilation errors (SyntaxError: Unterminated JSX contents). The converter detects all 14 official W3C void elements and guarantees they are terminated with a self-closing trailing slash (e.g. <img src="..." alt="..." />).

05

TypeScript React.FC Component Architecture

When generating production-ready code, the tool wraps the converted JSX in a clean TypeScript functional component with an extensible Props interface, including optional className, children (React.ReactNode), and typed event callbacks. This allows developers to immediately drop the generated component into Next.js, Vite, Remix, or Astro applications.
