Markdown is a lightweight markup language designed to be readable as plain text while still encoding structure — a hash for a heading, asterisks for emphasis, a dash for a list item. It became the default writing format for developers and writers because it's faster to type than HTML, survives copy-paste, and lives comfortably in a Git diff. But browsers don't understand Markdown; they understand HTML. So somewhere between writing and publishing, every Markdown document gets converted to real <h1>/<h2> headings, <strong> and <em> emphasis, <a> links, and <li> list items. This tool handles that common, everyday subset of Markdown and shows you both a live preview and the exact HTML it produces. It deliberately covers the syntax you reach for most — headings, bold, italic, links, and simple lists — rather than the full specification. For documents that use tables, task-list checkboxes, fenced code blocks with syntax classes, footnotes, or other GitHub-Flavored Markdown features, run them through a complete CommonMark parser such as markdown-it or marked, which implement the entire spec. For pasting a heading-and-paragraph draft, a simple README section, or notes into an HTML field, this converter is the quick path from Markdown to clean, copy-ready markup.
