# How to Convert Markdown to HTML Online

**Markdown to HTML** should be fast, faithful and free. Markdown Tools converts your Markdown into clean, semantic HTML in real time — paste on the left, copy the result on the right. No account, no upload, no install.

## Why convert Markdown to HTML?

- **Clean, portable markup** — semantic tags only; wrapper soup and unsafe attributes are stripped
- **Faithful rendering** — tables, task lists, footnotes and math survive the conversion
- **Publish-ready** — paste the fragment into a CMS, a blog theme or a static site generator

## Markdown to HTML: what is supported

## A worked example

Input stays plain Markdown; fenced code keeps its language tag:

```html
<article>
  <h1>Ship it</h1>
  <p>Semantic HTML in, readable Markdown out.</p>
</article>
```

A descriptive link, like the [Markdown syntax guide](https://www.markdownguide.org/basic-syntax/ "Markdown syntax guide"), keeps its anchor text and title. Images keep their alt text — which is what search engines actually read:

![A flower used as an image demo](https://upload.wikimedia.org/wikipedia/commons/thumb/3/3f/JPEG_example_flower.jpg/240px-JPEG_example_flower.jpg "Demo image")

Inline math such as $E = mc^2$ is typeset too, and exports as self-contained SVG.

> Good HTML starts with good Markdown. Keep the heading hierarchy clean and write alt text that describes the image.
