Markdown to HTML

Convert Markdown syntax to clean HTML with GitHub Flavored Markdown support and live preview.

Markdown Input

Use Markdown to HTML when…

You need HTML source to paste into a CMS, newsletter, email template, or static page.
You're exporting Markdown for tools that only accept HTML (Mailchimp, Substack, some WordPress importers).
You want GFM features (tables, task lists, fenced code, strikethrough) rendered correctly in the output HTML.

Just drafting and want a live editor experience? Use Markdown Preview instead — it's tuned for real-time editing rather than exporting the final HTML.

Introduction

Markdown to HTML takes a Markdown document and emits the equivalent HTML source. The converter runs the marked parser locally against your input and hands you back the HTML on the other side — ready to paste into an email template, a CMS field, or a static page.

Plain Markdown rarely lives on its own. Newsletters need HTML bodies, documentation platforms often expect pre-rendered HTML in their import format, and email clients only read HTML. This converter bridges that gap without spinning up a build pipeline: you paste Markdown, get HTML back, and copy it wherever you need it.

The parser supports GitHub Flavored Markdown (GFM), including tables, fenced code blocks, task lists, strikethrough, and automatic link detection. A preview tab renders the HTML so you can compare the source and the rendered output side by side.

How to Use

Paste your Markdown document into the input editor.
Switch to the HTML tab to read the generated markup.
Switch to the Preview tab to see how the HTML renders in the browser.
Click the copy button to put the HTML on your clipboard.
Download the HTML as a file when you need to commit it to a repository.

Examples

Example 1: GFM table

Input

| Plan     | Price | Seats |
| -------- | ----- | ----- |
| Free     | $0    | 1     |
| Team     | $12   | 5     |
| Business | $40   | 20    |

Output

<table>
  <thead>
    <tr><th>Plan</th><th>Price</th><th>Seats</th></tr>
  </thead>
  <tbody>
    <tr><td>Free</td><td>$0</td><td>1</td></tr>
    <tr><td>Team</td><td>$12</td><td>5</td></tr>
    <tr><td>Business</td><td>$40</td><td>20</td></tr>
  </tbody>
</table>

Example 2: Fenced code block with a language tag

Input

Quick sanity check:

```ts
function greet(name: string) {
  return `Hello, ${name}!`;
}
```

Returns the greeting string.

Output

<p>Quick sanity check:</p>
<pre><code class="language-ts">function greet(name: string) {
  return `Hello, ${name}!`;
}
</code></pre>
<p>Returns the greeting string.</p>

Example 3: Image with alt text and a link

Input

![Dashboard screenshot](/images/dashboard.png)

The latest build ships with [dark mode](/changelog#v2-1).

Output

<p><img src="/images/dashboard.png"
  alt="Dashboard screenshot"></p>
<p>The latest build ships with
<a href="/changelog#v2-1">dark mode</a>.</p>

Target language details

Version assumptions and style choices baked into the generated output. If your runtime is older, you may need to adjust syntax (e.g. drop optional chaining, use `var` instead of `const`).

Language	Version	Output style
Markdown	GitHub Flavored Markdown (GFM)	Tables, fenced code, task lists, strikethrough supported.

Key Features

Full GFM support: tables, task lists, strikethrough, fenced code, and automatic URL detection behave the way GitHub renders them.
Code + preview tabs: flip between the HTML source and the rendered view to confirm both forms are correct.
Copy and download: paste the HTML into a CMS, an email, or save it as a .html file.
Real-time conversion: the output refreshes as you type, so you never wait for a save-and-reload cycle.
Runs locally: the parser executes in the browser, so private drafts stay on your device.
Clean output: no inline styles, no tracking scripts, no wrapper divs — just the HTML the parser emits.

Frequently Asked Questions

Does the converter parse YAML front matter?

No. A leading --- block is treated as a thematic break followed by text. Strip the front matter before conversion if you want a clean HTML body.

Are task lists supported?

Yes. - [x] done and - [ ] todo render as checkbox list items in both the HTML source and the preview.

Will the HTML include syntax-highlighted code blocks?

The output tags code fences with class="language-xxx" attributes matching the fence, but no coloring is applied. Pair the output with a highlighter like Prism or highlight.js on the consuming side to get colors.

What happens if my Markdown contains raw HTML?

Raw HTML tags pass through to the output unchanged. That lets you drop in custom elements when Markdown syntax runs out, at the cost of bypassing sanitization. Always sanitize before publishing untrusted input.

Is there a size limit?

There is no hard cap. The practical ceiling is your browser's available memory — documents up to a few megabytes convert without noticeable latency.
