Which Markdown flavor is supported?

Standard CommonMark-style Markdown is parsed, including headings, lists, emphasis, links, and code blocks.

The preview renders the HTML produced from your own local input. Only paste content you trust, since the preview executes the markup.

Is my content uploaded?

No. The conversion runs entirely in your browser and nothing is sent to a server.
