What is it?

A Markdown-to-HTML converter takes the plain-text Markdown syntax (headings prefixed with #, bold with **, lists with -, etc.) and produces the corresponding HTML elements. The reverse is best-effort - HTML has more expressive power than Markdown, so any HTML that doesn't map to the Markdown subset is left alone.

When to use it

Drafting blog posts in Markdown and pasting the HTML into a CMS that lacks Markdown support. Converting a README into a webpage. Round-tripping content between a static-site generator (Markdown source) and a WYSIWYG editor (HTML source).

Common mistakes

Expecting GitHub-flavoured-Markdown extras (tables, task lists, ~~strikethrough~~) - they're not supported here. Pasting HTML with custom classes or attributes and expecting them to survive a round-trip - they get lost. And treating the converter as an HTML sanitiser - it isn't; do not paste untrusted HTML and embed the output in a page without escaping.
