Markdown to HTML Converter

Paste Markdown, get HTML. Live side-by-side preview.

The preview is sanitized (scripts and event handlers are stripped). The HTML source reflects the same sanitized output.

Convert Markdown to HTML in your browser

This Markdown to HTML converter turns Markdown source into clean HTML as you type, with a live side-by-side view. Paste or write Markdown in the left panel and switch the right panel between a rendered Preview and the raw HTML source. Headings, bold and italic text, lists, links, images, blockquotes, code blocks, and GitHub-flavored tables all convert instantly.

It is handy whenever content written in Markdown needs to live somewhere that only accepts HTML: a CMS body field, an email template, a static page, or a widget that takes raw markup. Instead of hand-writing tags or installing a build step, you convert once, click Copy HTML, and paste the result. Because the output updates on every keystroke, it also doubles as a quick Markdown previewer for checking a README or a blog draft before you commit it.

The conversion runs entirely in your browser, your text is never uploaded to a server. One caution shown on the page itself: the preview renders the generated HTML as-is, so if the Markdown comes from an untrusted source, sanitize the HTML output before publishing it anywhere.

How to convert Markdown to HTML

  1. Paste your Markdown

    Put the Markdown source in the left panel. Standard syntax plus GitHub-flavored extensions like tables are supported.

  2. Check the live preview

    The Preview tab renders the converted HTML as you type, so you can spot a broken list or a malformed link immediately.

  3. Switch to HTML source

    Click the HTML source tab to see the exact markup that was generated, with one element per Markdown construct.

  4. Copy the HTML

    In the HTML source view, click Copy HTML to put the converted markup on your clipboard, ready for your CMS, email template, or page.

Frequently asked questions

What is Markdown?

Markdown is a lightweight plain-text formatting syntax created by John Gruber in 2004. You write readable symbols like # for headings and ** for bold, and a converter turns them into HTML. It is the standard format for README files, documentation, and many blogging platforms.

How do I convert Markdown to HTML for free?

Paste your Markdown into the input panel of this tool, check the live preview, then open the HTML source tab and click Copy HTML. The conversion happens in your browser with no signup and no upload.

Does this converter support tables and code blocks?

Yes. It supports GitHub-flavored Markdown, so pipe-delimited tables, fenced code blocks, headings, lists, links, images, and blockquotes all convert to the corresponding HTML elements.

Is the generated HTML safe to publish?

Markdown allows raw HTML to pass through, so output converted from untrusted input can contain unwanted markup or scripts. If the Markdown is not your own, run the HTML through a sanitizer before publishing it on a live page.

Can I use this as a Markdown previewer?

Yes. The Preview tab renders your Markdown live as you type, which makes it a quick way to proof a README, blog post, or documentation page without committing or deploying anything.
