Which Markdown flavour is supported?

CommonMark basics plus the common GitHub-flavoured extras: tables, strikethrough, fenced code blocks and automatic links.

Is the HTML safe to publish?

The preview is sanitised before rendering. If you are publishing user-supplied Markdown, sanitise it again on your own server.

Is anything uploaded?

No. Conversion and preview both run in your browser.

Why did my HTML lose some styling?

Markdown has no way to express inline styles, classes or layout, so those are dropped when converting HTML to Markdown. Structure and content are preserved.
