Markdown to HTML Converter

The Markdown to HTML converter turns Markdown into clean HTML that you can paste into a website, a CMS, an email, or a documentation page. Write in the simple, readable Markdown syntax and get standards-compliant HTML with a live rendered preview underneath the output.

Supported syntax

  • Headings (# through ######), paragraphs, and emphasis (**bold**, *italic*, ~~strike~~).
  • Ordered, unordered, and nested lists, plus task lists (- [x] done).
  • Links, images, and automatic links for bare URLs.
  • Blockquotes and horizontal rules.
  • Inline code and fenced code blocks; a language hint becomes class="language-xyz" for highlighters like Prism or highlight.js.
  • Tables with column alignment.

Options

  • GitHub Flavored Markdown – enables tables, task lists, strikethrough, and autolinks. Turn it off for strict CommonMark output.
  • Line breaks as br – treat every newline as a hard break, matching GitHub issues and many chat apps.
  • Allow raw HTML – off by default for safety. When off, any HTML inside the Markdown is escaped and shown as text; when on, it is passed through unchanged.

Why convert Markdown to HTML?

Many publishing platforms only accept HTML, while Markdown is much faster to write and easier to review in Git. Converting lets you draft README-style content, release notes, or blog posts in Markdown and publish them anywhere. The output contains no inline styles, so it inherits your site's CSS.

Edit with a toolbar and live preview in the Markdown Editor, just read a document in the Markdown Viewer, or convert back with HTML to Markdown.

Frequently Asked Questions

Everything in CommonMark plus GitHub extensions: tables, task lists, strikethrough, autolinks, and fenced code blocks with a language class for syntax highlighters.

Raw HTML is escaped by default so pasted Markdown cannot inject scripts. Turn on "Allow raw HTML" if you trust the input and want tags like details or kbd to pass through.

By default a single newline inside a paragraph is treated as a space, as in standard Markdown. With this option every newline becomes a br, like on GitHub comments.

The conversion uses marked, a fast and widely used Markdown parser, running entirely in your browser.
