Paste the Markdown into a browser-based converter and it renders the equivalent HTML instantly, ready to copy into a page, a CMS or an email template. The conversion runs on your device, so unpublished drafts and internal docs are never uploaded.
Markdown, created by John Gruber in 2004 and later standardized as CommonMark, is what most people write READMEs, docs and posts in. Browsers only render HTML, so publishing means converting: headings become h tags, asterisks become emphasis, and fenced blocks become code elements. A converter with a live preview shows exactly what the output will look like as you type.
The conversion is useful anywhere a system wants HTML but you would rather write Markdown: CMS fields, email templates, help-center articles, static site content. Because the tool is client-side, a half-finished announcement or an internal runbook stays on your machine until you decide to publish it.
No. The conversion and preview run entirely in your browser.
The standard core: headings, emphasis, links, images, lists, blockquotes and code blocks.
Yes, though email clients have quirky CSS support, so keep the markup simple and test in your email tool.
