What Is Markdown to HTML?

Markdown is a lightweight markup for docs and web content. Browsers and CMS systems render HTML, not raw Markdown. This tool converts your Markdown into HTML—headings become h1-h6, links become a tags, code blocks become pre/code. The CommonMark spec defines the input; output follows standard HTML.

Conversion runs entirely in your browser. Nothing is sent to a server. The output is clean HTML. For the reverse (HTML to Markdown), use HTML to Markdown. For live preview while editing, use the Markdown Editor.

How to Use This Tool

1

Paste or Upload Markdown

Copy your Markdown and paste it into the left editor. You can also click Upload to load a .md or .markdown file. The Sample button loads example data.

2

View the HTML Output

The right panel shows the converted HTML. Headings, paragraphs, lists, links, images, and code blocks are converted. Copy or download for use in web pages or CMS.

3

Copy or Download

Use Copy or Download. For formatting Markdown first, use the Markdown Formatter. For validation, use the Markdown Validator.

When Markdown to HTML Helps

When publishing docs to a website, blog, or CMS that expects HTML, this conversion bridges the gap. Write in Markdown (faster, cleaner) and convert to HTML for embedding. Static site generators like Jekyll and Hugo do this at build time; this tool does it on demand. The W3C HTML spec defines the output format.

Email newsletters, documentation sites, and content management systems often need HTML. Converting Markdown here gives you the HTML to paste or import. For PDF output, use Markdown to PDF. For converting HTML back to Markdown, use HTML to Markdown.

Frequently Asked Questions

Does it support GitHub Flavored Markdown?

Most GFM features (tables, strikethrough, task lists) are typically supported. The output HTML reflects the Markdown structure. Check the result for edge cases.

Is my data private?

Yes. Conversion runs entirely in your browser. No data is sent to any server.

What about raw HTML in Markdown?

Raw HTML blocks in Markdown are typically passed through to the output. The converter preserves HTML you've embedded. Sanitization may apply—check the output.

Can I add CSS classes?

The default output uses standard HTML elements. For custom classes, you may need to post-process the HTML or use a Markdown extension that supports attributes.

Does it produce a full HTML document?

The output is typically the body content (headings, paragraphs, etc.). For a full document with html, head, and body, wrap the output or use a template.
