Markdown to HTML Converter

Convert Markdown syntax to clean HTML code.

Paste Markdown and get rendered HTML, with full GitHub-Flavored Markdown support: tables, task lists, fenced code blocks with language hints, autolinks and strikethrough. Inline HTML in the source passes through untouched.

Common use cases: rendering README or blog content for preview, generating HTML email bodies from Markdown drafts, exporting docs from a Markdown editor to a CMS that wants HTML, and prepping content for static-site generators.

Frequently asked questions

Which Markdown flavour does it use?
GitHub-Flavored Markdown (GFM): fenced code blocks, tables, task lists, autolinks, and strikethrough — the dialect most developers expect. Standard CommonMark for everything not GFM-specific.
Does it support inline HTML inside Markdown?
Yes — CommonMark explicitly allows passthrough of inline and block HTML. <sub>, <sup>, custom <div> wrappers, and the like flow through to the output unchanged.
Is the output safe to inject into a page?
Not without sanitisation. The output is exactly what the Markdown produces — including any inline <script> tags if they were in the input. For user-submitted Markdown rendered to HTML, run the result through DOMPurify or an equivalent sanitiser before innerHTML'ing it.
How do I get syntax highlighting in code blocks?
The converter outputs <pre><code class="language-X"> for fenced blocks with a language hint. Pair the output with a highlighter like highlight.js or Prism on your page to colourise it.
