Markdown vs HTML: What Is the Difference?
By the MDConverter team · Updated · 3 min read
Quick answer
Markdown is a shorthand for writing; HTML is the language browsers display. Markdown is converted into HTML: **bold** becomes <strong>bold</strong> and # Title becomes <h1>Title</h1>. Markdown is faster to write and easier to read, but covers only common structure; HTML can express anything a web page can, at the cost of verbosity. Most Markdown renderers let you mix the two when you need something Markdown cannot do.
The same content in both

## Shopping list
Buy **fresh** bread and:
- Milk
- [Coffee](https://example.com)<h2>Shopping list</h2>
<p>Buy <strong>fresh</strong> bread and:</p>
<ul>
<li>Milk</li>
<li><a href="https://example.com">Coffee</a></li>
</ul>Same structure, about half the characters, and the Markdown reads naturally even before it is rendered.
Side-by-side comparison
| Markdown | HTML | |
|---|---|---|
| Purpose | Writing content quickly | Describing any web page |
| Readable as raw text | Yes | Hard |
| Expressiveness | Headings, emphasis, lists, links, images, code, tables | Everything: forms, layouts, media, attributes, scripts |
| Styling | None (the app decides) | Classes, inline styles, CSS |
| Learning time | Minutes | Days to weeks |
| Safety for user content | High (limited syntax, HTML often filtered) | Needs careful sanitizing |
| Where it is used | READMEs, notes, docs, chat, AI answers | Websites, emails, apps |
Mixing HTML into Markdown
CommonMark allows raw HTML, so you can drop in an element when Markdown has no syntax for it — collapsible sections, image sizing, <kbd> keys, <sup> and <sub>:
Press <kbd>Ctrl</kbd> + <kbd>S</kbd> to save.
<details>
<summary>More options</summary>
Markdown **works** in here too.
</details>Press Ctrl + S to save.
More options
Markdown works in here too.
Two rules: leave blank lines around block-level HTML if you want Markdown processed inside it, and expect platforms to filter some tags — GitHub removes <script>, <style>, <iframe> and style attributes, and chat apps usually remove all HTML.
When to use which
Use Markdown for documentation, READMEs, notes, blog posts in a static site, knowledge bases, anything versioned in Git, and text you will feed to AI models.
Use HTML for page layouts, forms, interactive elements, email templates, and anywhere you need precise control of appearance.
Use both when a mostly-text document needs a few elements Markdown lacks.
Markdown vs rich text (Word, Google Docs)
Rich-text editors hide the markup and store formatting in their own file formats. Markdown keeps formatting visible as characters in a plain-text file. That makes Markdown portable and diff-friendly, and rich text friendlier for people who never want to see markup. Converting between them is routine: Markdown to Word, Word to Markdown, Markdown to Google Docs and Google Docs to Markdown. For plain Rich Text Format files from TextEdit or WordPad there are Markdown to RTF and RTF to Markdown.
Converting between Markdown and HTML
- Markdown to HTML — clean HTML5 for a website or CMS, with optional standalone page and syntax highlighting.
- HTML to Markdown — paste HTML code or content copied from a web page.
- URL to Markdown — fetch a public web page and keep only its main content as Markdown.
