Frequently Asked Questions

Markdown is a lightweight plain-text formatting syntax created by John Gruber in 2004. It lets you write formatted documents using simple symbols like # for headings, ** for bold, and - for lists, which are then converted to HTML. It is widely used for README files, documentation, blogs, wikis, and content management systems.

GitHub Flavored Markdown (GFM) is GitHub's extended Markdown spec. It adds tables, task lists (- [ ] item), fenced code blocks with syntax highlighting, strikethrough text (~~text~~), and autolinks. When the GFM toggle is on, this tool processes all of these extensions.

Yes. Fenced code blocks with a language identifier (e.g. ```javascript) are highlighted using highlight.js, which supports over 180 programming languages. The colors appear in both the preview and in the downloaded HTML file.

Click Copy HTML to copy the output to your clipboard, or Download .html to save it as a file. Enable Wrap Full HTML to get a complete standalone HTML5 document with doctype, head, and body, including your custom CSS.

When Auto TOC is enabled, the converter scans all headings (H1–H6) in your Markdown and generates a nested, anchor-linked table of contents at the top of the output. Each heading gets an id attribute for deep linking.

Yes. Click Custom CSS to open the CSS editor. Anything you write there is injected into the live preview iframe and included in the exported HTML. This lets you fully control typography, colors, spacing, and layout of the rendered document.

Completely. All Markdown parsing and HTML generation happens inside your browser using JavaScript. Nothing is sent to any server. You can even use this tool offline after the page first loads.

Why Use a Markdown to HTML Converter?

Markdown has become the go-to format for writing content in the developer ecosystem — from GitHub README files to documentation sites, technical blogs, and static site generators. Its plain-text syntax is easy to write and read, but the final deliverable for the web is always HTML. A reliable converter bridges that gap instantly.

What Makes a Good Markdown Converter?

A basic converter just turns # Heading into <h1>. A great one handles the full GitHub Flavored Markdown spec, provides a live preview so you see exactly what you'll get, applies syntax highlighting to code blocks, and gives you export options suited to your workflow — whether that's a snippet to paste into a CMS or a complete standalone HTML page.

GitHub Flavored Markdown vs Standard Markdown

Standard Markdown (CommonMark) covers headings, paragraphs, bold, italic, links, images, lists, blockquotes, code, and horizontal rules. GFM adds:

  • Tables — pipe-separated columns with alignment control
  • Task lists- [ ] and - [x] render as interactive checkboxes
  • Fenced code blocks — triple backticks with a language identifier for syntax highlighting
  • Strikethrough~~double tilde~~ produces struck-through text
  • Autolinks — bare URLs are automatically converted to clickable links

When to Use "Wrap in Full HTML Document"

Use this option when you need a completely self-contained .html file — for example, to email a document, host a simple page, or share an offline reference. The full document includes a valid doctype, charset declaration, viewport meta tag, and embeds any custom CSS you've written directly into the head.

When embedding the content into an existing page or CMS, leave this off to get just the body fragment — a clean block of HTML ready to paste anywhere.
