The conversion runs in this browser tab, with no account or upload. The optional GitHub mode handles tables, task lists, strikethrough and extended autolinks alongside standard Markdown.

How do you convert Markdown to HTML?
A Markdown to HTML converter parses plain-text Markdown markers and returns semantic HTML for headings, paragraphs, links, lists, tables, quotes and code. Paste your source to update the HTML live, inspect it in a sandboxed preview, then copy the fragment or download it as an HTML file.
How to use
- 1Paste your Markdown. Type in the editor, paste from your clipboard or load the sample document.
- 2Choose parsing options. Keep GitHub features on for tables and task lists, and enable single line breaks only when your target expects them.
- 3Check the result. Read the generated HTML source or switch to the isolated rendered preview.
- 4Copy or download. Copy the HTML fragment to your project or save it as an .html file.
Who it's for
- Developers can turn README sections and documentation into HTML for a website or CMS.
- Technical writers can inspect the tags produced by headings, lists, links, quotes and code blocks.
- Content editors can prepare an HTML fragment from Markdown without installing a command-line converter.
- Email and knowledge-base teams can create reusable HTML before applying their own styles or templates.
FAQ
Is my Markdown uploaded?
No. Parsing, HTML generation and the rendered preview run in your browser. The preview also blocks scripts and remote resources, so pasted HTML cannot execute code or fetch an external image while you inspect the result.
Is this Markdown to HTML converter free?
Yes. You can convert, preview, copy and download HTML without an account or payment. There is no server-side conversion queue because the parser runs locally in the current browser tab.
How much Markdown can I convert?
The editor accepts up to 1,000,000 JavaScript characters per conversion. That explicit cap keeps live updates responsive for large README files and documentation drafts. Unicode characters outside the basic multilingual plane can occupy two JavaScript character units.
Does it support GitHub Flavored Markdown?
Yes. GitHub features are enabled by default, including tables, task-list items, strikethrough and extended autolinks. Turn the option off when you need output closer to core Markdown rather than GitHub's common extensions.
What happens to raw HTML inside Markdown?
Raw HTML is preserved in the generated source because Markdown permits embedded HTML. Treat copied output as untrusted if another person supplied the input. The on-page preview is sandboxed and uses a restrictive content security policy, but your destination should sanitize untrusted HTML before publishing it.
Why do single line breaks not become br tags?
Standard Markdown treats a single newline inside a paragraph as a soft break, usually rendered as a space. Enable Single line breaks when you want each newline to produce an HTML line-break element instead.
Can I convert Markdown code blocks and tables?
Yes. Fenced and indented code blocks become HTML preformatted-code elements. Pipe tables become HTML tables while GitHub features are enabled. The converter preserves a fenced code block's language label as a class that a separate syntax-highlighting library can use.
