# Markdown to HTML and back

Turn Markdown into HTML with a live preview, or HTML back into Markdown.
Markdown → HTMLHTML → MarkdownMarkdown

Converts automatically 400ms after you stop typing (the button forces it now).
Convert

- Markdown → HTML drops raw HTML by design (no allowDangerousHtml): the fold list names it when it happens.
- HTML → Markdown is lossy by nature: divs flatten, spans unwrap, inline styles vanish, every fold is listed, none silent.
- No syntax highlighting, footnotes, or math extensions. GFM is the whole grammar here.
Paste, drop, or type to begin. Everything stays on this device.
