Markdown to HTML Converter

How to Use

1. Enter or paste your Markdown text into the input area.
2. Make sure your Markdown includes supported elements like headings, bold or italic text, links, images, code blocks fenced with ```, tables, task lists, blockquotes, and horizontal rules.
3. The tool automatically converts the Markdown to HTML using semantic tags such as <h1>-<h6>, <strong>, <em>, and <pre><code>.
4. Review the generated HTML output displayed in a separate pane.
5. Copy the resulting HTML code for use in your projects or further editing.

How It Works

This converter uses the marked JavaScript library, which implements the CommonMark specification with GitHub Flavored Markdown (GFM) extensions. The parser recognizes various Markdown constructs—ranging from headings indicated by 1 to 6 hash marks (# to ######), strong and emphasized text for bold and italic, to fenced code blocks designated by triple backticks (```).

The library outputs semantic HTML5 tags: headings are converted to <h1> through <h6>, bold text to <strong>, italics to <em>, and code blocks wrapped in <pre><code> for proper formatting and accessibility. Tables follow the GFM specification using <table>, <thead>, <tbody>, and related tags for structure. Task lists are rendered as checkboxes within list items.

All processing happens within your browser, so your Markdown content never leaves your device, ensuring data privacy and quick conversions without network latency.

Example

# Sample Heading

This is a **bold** text and this is *italic*.

- [x] Completed task
- [ ] Pending task

```javascript
console.log('Hello, world!');
```

| Column 1 | Column 2 |
| -------- | -------- |
| Cell 1   | Cell 2   |

> This is a blockquote.
