All Markdown parsing runs entirely in your browser using the marked library. Your text is never sent to any server.

Markdown has become the universal language of technical writing — from README files and documentation to blog posts, forum comments, and chat messages. Our free Markdown to HTML Converter transforms plain-text Markdown into clean, semantic HTML with a live rendered preview that updates on every keystroke. Powered by the battle-tested marked library, it supports the full GitHub Flavored Markdown (GFM) specification including tables, fenced code blocks, task lists, strikethrough, autolinks, and raw HTML passthrough. Toggle between the rendered preview and raw HTML source, copy the output with one click, or download a complete, self-contained HTML document ready for publishing.

How to Use the Converter

  1. Write or paste Markdown — Enter your Markdown text in the left panel. The converter supports headings, bold, italic, links, images, lists, code blocks, blockquotes, horizontal rules, and GFM tables.
  2. Watch the live preview — The right panel renders your Markdown as styled HTML in real-time. Headings, lists, tables, and code blocks appear exactly as they would on GitHub or a static site.
  3. Toggle HTML Source — Switch to the HTML Source tab to see the raw, unrendered HTML output. This is useful for copying the markup directly into a CMS, email template, or static page.
  4. Copy or download — Click Copy HTML to grab the output to your clipboard, or Download to save a complete HTML document with embedded base styles ready for publishing.

Key Features

  • GFM Tables

    Full support for GitHub Flavored Markdown tables with header rows, alignment, and inline formatting.

  • Fenced Code Blocks

    Triple-backtick code blocks preserve indentation and are escaped for safe HTML embedding.

  • Live Preview

    Rendered HTML preview updates on every keystroke — see exactly how your content will look before publishing.

  • Toggle Source/Preview

    Switch between rendered preview and raw HTML with one click — perfect for copying into a CMS or email.

  • One-Click Export

    Copy raw HTML to clipboard or download a complete, styled HTML document ready for immediate publishing.

  • 100% Client-Side

    Parsing uses the marked library directly in your browser. No server round-trips — your content stays private.

When to Use a Markdown to HTML Converter

  • Content Publishing: Write blog posts, documentation pages, or newsletters in Markdown and convert them to HTML for your CMS, static site generator, or email platform.
  • README to HTML: Transform your project's README.md into a styled HTML page for documentation sites, GitHub Pages, or internal wikis.
  • Email Templates: Write email content in readable Markdown and convert to HTML for sending rich-text newsletters through Mailchimp, SendGrid, or custom systems.
  • CMS Migration: Many headless CMS platforms accept HTML but not Markdown. Batch-convert your Markdown content to HTML for import into WordPress, Contentful, or Sanity.
  • Quick Prototyping: Draft page content in Markdown and preview it as styled HTML before wiring it up to a backend or template engine.

Frequently Asked Questions

What is GitHub Flavored Markdown (GFM)?
GFM is GitHub's extended Markdown specification that adds tables, strikethrough, task lists, autolinks, and fenced code blocks with language identifiers to the original Markdown syntax. It's the most widely used Markdown dialect — adopted by GitLab, Bitbucket, Discord, Slack, Notion, and countless developer tools. Our converter implements the full GFM spec via the marked library.
Can I include raw HTML in my Markdown?
Yes. The converter passes through raw HTML embedded in your Markdown. This lets you use custom elements, add inline styles, or embed iframes and video players that aren't part of the standard Markdown syntax. Be aware that passing raw HTML may include script execution in some contexts — always sanitize user-generated Markdown before rendering on a live site.
Does the converter handle code syntax highlighting?
Code blocks are wrapped in <pre><code> tags with a language class (e.g., language-javascript) that's compatible with syntax highlighting libraries like Prism.js and highlight.js. The converter itself does not apply colors — for that, add a highlighting library to your page.
Is the downloaded HTML ready to publish?
Yes. The Download button generates a complete, self-contained HTML document with DOCTYPE, charset meta tag, responsive viewport, and embedded CSS for typography, code blocks, tables, and blockquotes. The output is styled with a clean, modern system font stack and looks professional out of the box.
Is my content safe and private?
Absolutely. All Markdown parsing runs entirely in your browser using the marked library. Your text never leaves your device — no uploads, no server processing, no logging. You can disconnect from the internet and the converter continues working without interruption.
