Markdown to HTML

The Markdown to HTML converter turns a Markdown document into clean, ready-to-paste HTML without installing anything or sending your text to a server.

It supports the everyday Markdown you actually write: ATX headings from H1 to H6, bold and italic emphasis, inline code, fenced and indented code blocks, ordered and unordered lists, blockquotes, horizontal rules, links and images.

Paragraphs are grouped sensibly and blank lines start new ones, so the output mirrors how the document reads.

You can flip between the raw HTML source — handy for pasting into a template, email or CMS — and a rendered preview that shows roughly how a browser will display it.

Safety is built in.

Every piece of text is HTML-escaped before any Markdown markers are applied, and raw HTML in the source is escaped rather than passed through, so the converter never emits an unexpected tag or script from your input.

That makes the output safe to drop into a page without a separate sanitising step.

Because the conversion runs entirely in your browser, nothing you paste is uploaded, logged or stored, and it keeps working offline once the page has loaded.

That makes it well suited to private notes, internal docs and draft content you would rather not send through an online service.
