About this tool
Convert Markdown to clean HTML instantly with this free online converter. Paste your Markdown text — headings, bold, italic, links, lists, code blocks, tables — and get properly formatted HTML ready to use in your website, blog, email template, or CMS. The converter supports GitHub Flavored Markdown (GFM) including tables, strikethrough, task lists, and autolinks. Toggle between viewing the raw HTML source code (for copy-pasting into your project) and a rendered preview (to see how it will look in a browser). The conversion handles nested lists, fenced code blocks with language hints, block quotes, horizontal rules, and inline code. All processing runs entirely in your browser — your text is never sent to a server or stored anywhere. Whether you are writing documentation, preparing a blog post, converting README files, or building email templates from Markdown source, this tool gives you clean, standards-compliant HTML output.
Frequently Asked Questions
Markdown is a lightweight text formatting language created by John Gruber in 2004. It uses simple symbols — # for headings, ** for bold, * for italic, - for lists — to format text without a visual editor. Markdown files (.md) are used for README files on GitHub, documentation, blog posts, and technical writing. It converts cleanly to HTML while remaining readable as plain text.
GFM is GitHub's extended version of standard Markdown. It adds tables (using | pipes), strikethrough (~~text~~), task lists (- [x] done, - [ ] todo), autolinked URLs, and fenced code blocks with syntax highlighting hints (```javascript). This converter supports all GFM features, so your GitHub README content will convert correctly.
The converter produces standard, well-formed HTML. If you are converting your own Markdown for your own site, the output is safe to use directly. If you are converting untrusted user-submitted Markdown, you should sanitize the HTML output with a library like DOMPurify before inserting it into your page to prevent XSS attacks.
This tool converts Markdown to HTML only (one direction). Converting HTML back to Markdown is a much more complex problem because HTML can represent structures that have no Markdown equivalent. For HTML-to-Markdown conversion, look for tools that use libraries like Turndown.js.
No. All Markdown-to-HTML conversion happens entirely in your browser using the marked.js library. No text is transmitted, stored, or logged. Your content stays completely private on your device.
