About Markdown and HTML

Markdown is the lightweight syntax behind READMEs, issues, docs and many CMSes; HTML is what browsers render. Converting Markdown to HTML is handy when a system only accepts HTML, and the reverse (HTML → Markdown) helps when migrating content into a Markdown-based site or docs tool. Both run locally so your content never leaves the page.

Frequently asked questions

Which Markdown flavor is supported?
CommonMark with GitHub-flavored extensions (tables, fenced code, strikethrough, task lists, autolinks) via the marked parser.
Can it convert HTML back to Markdown?
Yes — switch the direction to HTML → Markdown. It uses Turndown to produce clean Markdown from HTML.
Is the HTML output safe to publish?
It reflects exactly what your Markdown describes. Since you control the input, treat the output as your own content. We show it as source for you to copy, not as a live rendered page.
Is anything uploaded?
No — conversion runs entirely in your browser.
