Free Online Markdown to HTML Converter with Live Preview
Markdown is the most popular lightweight markup language for writing content — used in GitHub READMEs, documentation sites, blogs, and CMS platforms. Our free Markdown to HTML converter transforms your Markdown into clean, semantic HTML as you type. Switch between the raw HTML source and a live rendered preview to see exactly how the output will look. When you are satisfied, copy the HTML to your clipboard or download it as a ready-to-use .html file.
What Gets Converted
The converter handles the full CommonMark specification plus GitHub Flavored Markdown (GFM) extensions: headings, bold and italic emphasis, ordered and unordered lists, links and images, fenced code blocks with language classes, blockquotes, horizontal rules, tables, strikethrough text, task lists, and auto-linked URLs. The real-time preview renders everything instantly so you can verify the result before copying or downloading.
Why Convert Markdown to HTML
Static site generators like Hugo, Jekyll, and Gatsby convert Markdown during the build, but you sometimes need to preview or extract HTML manually. Email newsletters do not support Markdown — if you write in Markdown, you need HTML for platforms like Mailchimp or ConvertKit. Many CMS platforms do not natively support Markdown; converting to HTML and downloading the file lets you paste or upload content anywhere with confidence.
Frequently Asked Questions
Which Markdown specification does this tool follow?
The tool uses Marked.js, which follows CommonMark with GitHub Flavored Markdown (GFM) extensions: tables, strikethrough, task lists, and auto-linked URLs. The live preview renders the output in real time so you can verify every element.
Does the converter add CSS styling to the HTML?
No. The output is clean, semantic HTML without inline styles or CSS classes. You control styling with your own stylesheet. The downloaded .html file contains only the converted markup.
Can I download the converted HTML?
Yes. Click the "Download .html" button to save the converted output as a file. You can also copy the HTML to your clipboard with the Copy button.
Can I convert HTML back to Markdown?
Yes — use our HTML to Markdown Converter tool for the reverse conversion.
Does it support syntax highlighting in code blocks?
The raw HTML output includes language classes (e.g., class="language-javascript") that work with client-side highlighters like Prism.js or Highlight.js. The live preview renders code blocks with basic styling.
