Markdown to HTML Converter

Paste Markdown on the left and copy semantic HTML source from the right. GFM tables, task lists, strikethrough, and fenced code blocks are supported.

Convert Markdown to semantic HTML

The Markdown-to-HTML converter transforms plain Markdown into semantic HTML source. It supports GitHub Flavored Markdown features including tables, task lists, strikethrough, autolinks, and fenced code blocks with language classes.

Conversion happens in your browser, so mdkit does not upload your Markdown to a conversion server. This is useful when you're migrating content into a CMS that accepts HTML, generating static-site output, or adapting a README for a non-Markdown platform.

The generated HTML uses standard tags (<h1>–<h6>, <p>, <ul>, <ol>, <table>, <pre>, <code>) without inline styling or framework-specific classes. Fenced code blocks can include a language class for a separate syntax highlighter.

Markdown-to-HTML example

A heading, list, and bold phrase become standard HTML elements that you can style in your site or CMS.

Input
# Release notes

- Added **dark mode**
- Fixed the login issue
Output
<h1>Release notes</h1>
<ul>
  <li>Added <strong>dark mode</strong></li>
  <li>Fixed the login issue</li>
</ul>

How to use the Markdown to HTML Converter

  1. 1

    Paste your Markdown

    Paste or type Markdown into the left editor panel. GFM features like tables and task lists work out of the box.

  2. 2

    Review the HTML source

    The right panel shows HTML source updated in real time as you edit.

  3. 3

    Copy the HTML

    Click the copy button above the output to put the HTML on your clipboard, ready to paste into your CMS or editor.

Limits to know before you publish

  • The output is an HTML fragment, not a complete document with <html>, <head>, or CSS.
  • Raw HTML already present in the Markdown can pass through. Sanitize untrusted input before publishing it.
  • Language classes are preserved on fenced code blocks, but syntax colors require a separate highlighter on the destination site.

Common use cases

  • Migrating a README or docs site into a WordPress, Ghost, or other CMS that accepts HTML
  • Creating a semantic HTML starting point for a newsletter template
  • Converting a batch of Markdown notes for posting to a platform that doesn't accept Markdown
  • Previewing exactly how a Markdown document will render as HTML before committing

Frequently Asked Questions

Does this tool support GitHub Flavored Markdown (GFM)?+
Yes. Tables, task lists, strikethrough, autolinking URLs, and fenced code blocks with language hints all render correctly. The converter uses a GFM-compatible parser under the hood.
Is my Markdown sent to a server?+
No. Conversion runs in your browser via JavaScript. mdkit does not upload the document text to a conversion server.
Can I export the HTML as a file?+
Not directly from this tool, but you can copy the HTML and paste it into any text editor, then save with a .html extension. For styled output with embedded CSS, see the Markdown to PDF tool.
Does the HTML output include CSS styles?+
No. The output has no inline CSS or framework-specific classes. Fenced code blocks can include a language class such as language-js so your destination site can apply syntax highlighting.
Why is my HTML missing syntax highlighting on code blocks?+
The converter emits <pre><code class="language-xxx">…</code></pre> — the standard format. Syntax coloring is applied at render time by a highlighter library (Prism, highlight.js, Shiki) on your target site.
