MDMarkdown โ HTML Converter
Markdown is a lightweight markup language that lets you write formatted documents using plain text. It is widely used in GitHub READMEs, technical blogs, wikis, and documentation platforms โ all of which ultimately render Markdown as HTML. Conversely, converting existing HTML back to Markdown makes content easier to version-control and maintain. This tool supports bidirectional conversion with practical options: GFM (GitHub Flavored Markdown) tables and task lists, KaTeX math expressions, and flexible HTML output formatting (Pretty, Minify, Raw).
How to Use
- 1Choose conversion direction
Select 'Markdown โ HTML' or 'HTML โ Markdown' at the top. Your input is preserved when you switch modes.
- 2Configure options
In Markdown โ HTML mode you can choose the HTML output format (Pretty / Minify / Raw), toggle GFM support (tables and checkboxes), and enable KaTeX math rendering. In HTML โ Markdown mode you can set the heading style (ATX or Setext), bullet marker (-, *, +), code block style (Fenced or Indented), and specify tags to keep as raw HTML.
- 3Paste input or load an example
Paste text into the left pane or click 'Load Example' to load sample content. Conversion runs automatically after a short debounce and the result appears on the right.
- 4Check the live preview
The preview pane at the bottom shows the rendered output. In Markdown โ HTML mode it renders the converted HTML; in HTML โ Markdown mode it re-renders the Markdown result so you can verify the round-trip.
- 5Copy the result
Click the copy button next to the output to send the converted text to your clipboard.
Tips
- ๐กPaste your GitHub README into Markdown โ HTML mode to preview exactly how it will render on GitHub before you push.
- ๐กConverting HTML blog posts to Markdown makes them much easier to version-control and edit in the future.
- ๐กKaTeX math uses standard LaTeX syntax: $inline formula$ or $$block formula$$. Example: $E=mc^2$.
- ๐กGFM table syntax (| Col | Col |) and task lists (- [ ] item) are automatically converted to their Markdown equivalents when converting HTML โ Markdown.
- ๐กUse 'Keep Tags' to preserve specific HTML tags as-is during HTML โ Markdown conversion โ useful for custom elements or complex tables you want to keep in HTML.
- ๐ก'Pretty' outputs indented, readable HTML. 'Minify' strips whitespace for the smallest possible file size. 'Raw' gives you the exact output from the marked parser.
