Markdown to HTML and HTML to Markdown

Paste Markdown and get clean HTML with GitHub Flavored Markdown extensions (tables, task lists, fenced code with language). Or paste HTML and get readable Markdown with the right code style and link handling. Switch direction with one click. Both directions run in your browser, the text never goes anywhere.

How it works

Markdown to HTML uses the marked parser with GFM enabled. HTML to Markdown uses turndown with ATX headings, fenced code blocks and dash bullet lists. Both ship in the browser bundle, no server involved.

How to use it

  1. Paste markdown or HTML

    Drop in either format. Tables, code blocks, links, images and most CommonMark and GFM extensions parse correctly.

  2. Pick the conversion direction

    Switch between markdown to HTML and HTML to markdown. The toggle swaps editor and preview without losing your input.

  3. Watch the live preview

    Output renders as you type. Headings, lists and inline formatting update instantly so you can iterate on the source.

  4. Copy the converted result

    Grab the output for a README, a blog post, a CMS field or an email. Both editors keep their content for further edits.

Use cases

Convert a README.md to HTML for a static site.

Migrate a blog post from a WYSIWYG editor (HTML) to a Markdown CMS.

Quickly render a Markdown snippet to copy into a non Markdown tool.

Inspect what a Markdown parser actually generates from a tricky input.

Your data never leaves your browser

Every utility runs entirely on your device. Nothing is uploaded, nothing is stored on a server. You can disconnect from the internet and they keep working.
