Markdown to HTML / JSX Converter
Convert Markdown to clean HTML or React JSX with GFM and syntax highlighting
About this tool
This tool converts Markdown text into clean, semantic HTML or React JSX. It supports GitHub-Flavored Markdown (tables, task lists, strikethrough, autolinks), optional syntax highlighting for fenced code blocks, optional raw-HTML pass-through, an XSS-safe sanitization mode, and a JSX output mode that rewrites HTML attributes to their React equivalents (class→className, for→htmlFor, tabindex→tabIndex) and self-closes void tags. Use it to generate HTML or JSX for blog posts, documentation, email templates, or static-site generators. All parsing happens locally in your browser — nothing is uploaded.
Examples & Use Cases
Basic Markdown to HTML
<!-- Markdown Input -->
# Hello World
This is a **bold** and *italic* paragraph.
- Item 1
- Item 2
<!-- HTML Output -->
<h1>Hello World</h1>
<p>This is a <strong>bold</strong> and <em>italic</em> paragraph.</p>
<ul>
<li>Item 1</li>
<li>Item 2</li>
</ul>Headings, emphasis, and lists convert to their semantic HTML equivalents.
GitHub-Flavored Markdown (tables, task lists)
<!-- Markdown Input -->
| Name | Age |
| ---- | --- |
| John | 30 |
- [x] Done
- [ ] Todo
<!-- HTML Output -->
<table>
<thead><tr><th>Name</th><th>Age</th></tr></thead>
<tbody><tr><td>John</td><td>30</td></tr></tbody>
</table>
<ul>
<li><input disabled type="checkbox" checked>Done</li>
<li><input disabled type="checkbox">Todo</li>
</ul>Enable GFM to render tables and task-list checkboxes. The GFM plugin is on by default.
Code Block with Syntax Highlighting
<!-- Markdown Input -->
```js
const sum = (a, b) => a + b;
```
<!-- HTML Output (highlighted) -->
<pre><code class="hljs language-js">...</code></pre>Fenced code blocks get syntax-highlight classes when highlighting is enabled — pair with a highlight.js CSS theme.
