Markdown to HTML converter: the tool with a sample file converted

Where to use the HTML

Paste it into a CMS, an email template, a static site or a documentation tool that does not accept Markdown.

Security note

The output is raw HTML generated from your Markdown. If the Markdown comes from someone else, sanitize the HTML before publishing it on a website.

What the output contains

You get an HTML fragment (headings, paragraphs, lists, links, tables, code blocks), not a full page with <html> and <head>, so it can be pasted into a CMS, an email template or an existing page. It carries no CSS: your site's styles apply. GitHub-flavored extras are on: tables, strikethrough, task lists and automatic links. Raw HTML written inside the Markdown is passed through unchanged.

How to use

  1. Drop your file in the box above, or click to pick it.
  2. Wait a few seconds while it converts locally.
  3. Copy the result or download it.
