Markdown to HTML converts CommonMark-compliant Markdown into clean, semantic HTML — including GitHub Flavored Markdown extensions like tables, task lists, strikethrough, and fenced code blocks with language hints. The output uses the correct block elements (`<h1>–<h6>`, `<blockquote>`, `<ul>`, `<pre><code>`, `<table>`) so it inherits your site's stylesheet cleanly, and inline code is syntax-highlighted through `class="language-*"` labels that work with Prism or highlight.js. The conversion runs client-side in your browser, so unpublished drafts stay private. A live side-by-side preview updates as you type, and a ‘Copy HTML’ button gives you production-ready markup for a CMS, static-site generator, or email template. Sanitisation is on by default: raw `<script>` tags are stripped so pasted Markdown from an untrusted source cannot execute JavaScript in your preview.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
