# Rich Text to Markdown

An imported Claude artifact. Copy formatted content from a document, a web
page, an email or a note and paste it in: the HTML flavour of the clipboard is
sanitised, converted to Markdown, and rendered back as a preview so you can see
what the conversion produced before you take it away.

Headings, lists, links, emphasis, code and tables survive the trip; the styling
noise that a rich-text paste normally drags along does not.

Unlike a clipboard converter tied to one source application, this handles a
paste from anywhere, and it sanitises the incoming HTML before touching it.

The three libraries it uses - DOMPurify for sanitising, Turndown for the HTML to
Markdown conversion, marked for the preview - are served from this app rather
than a CDN, so the page loads no third-party code. Everything runs in the
browser: nothing is uploaded, no model is called, and nothing is metered.
