About Markdown and HTML
Markdown is the lightweight syntax behind READMEs, issues, docs and many CMSes; HTML is what browsers render. Converting Markdown to HTML is handy when a system only accepts HTML, and the reverse (HTML → Markdown) helps when migrating content into a Markdown-based site or docs tool. Both run locally so your content never leaves the page.
