Markdown Converter

Convert Markdown (CommonMark and GitHub-Flavored) to clean semantic HTML with live preview. Handles headings, tables, code blocks, images, and lists for READMEs and blog posts.

Why Use Markdown Converter?

Most CMS and email tools don't let you paste Markdown directly — they want HTML. Rather than wiring up a build step or hand-writing tags, a converter gives you a live preview and clean semantic HTML you can copy into WordPress, Ghost, Mailchimp, or a `<div dangerouslySetInnerHTML>` in React. It's also the fastest way to debug why your README renders one way on GitHub and another in your docs site: compare the rendered preview here with what you see in production.

How to Use Markdown Converter

  1. Write or paste your Markdown text in the left editor panel.
  2. View the live HTML preview on the right panel in real-time as you type.
  3. Switch between rendered preview and raw HTML code view, then copy the output.

Worked Examples

Convert a blog intro with a link

Input
## Why TypeScript?\nTypeScript adds **static types** to JavaScript. See [the handbook](https://www.typescriptlang.org) for details.
Output
<h2>Why TypeScript?</h2>\n<p>TypeScript adds <strong>static types</strong> to JavaScript. See <a href="https://www.typescriptlang.org">the handbook</a> for details.</p>

The converter wraps loose text in `<p>` tags automatically — no manual paragraph markup required.

Render a fenced code block

Input
```js\nconst hello = 'world';\n```
Output
<pre><code class="language-js">const hello = 'world';\n</code></pre>

The `language-js` class works with any syntax-highlighting library (Prism, highlight.js, Shiki).

GitHub-Flavored table

Input
| Tool | Stars |\n|------|-------|\n| React | 220k |\n| Vue | 205k |
Output
A semantic `<table>` with `<thead>` and `<tbody>`, ready for CSS.

Plain CommonMark parsers don't support tables — make sure GFM is enabled.

About Markdown Converter

The Markdown Converter transforms Markdown syntax into clean, standards-compliant HTML in real-time. Markdown is the preferred writing format for developers, technical writers, and content creators because of its simplicity and readability. Our converter supports the full Markdown specification including headings, bold, italic, links, images, code blocks, lists, tables, and blockquotes. The live preview panel shows exactly how your content will render, while the code view gives you the raw HTML to paste into your website, CMS, or email templates. Whether you're writing README files, blog posts, or documentation, this tool makes the Markdown-to-HTML workflow seamless.

Troubleshooting & Common Issues

Line breaks inside a paragraph disappeared

Markdown collapses single newlines into a space. For an actual `<br>`, end the line with two spaces + newline, or use the "hard_break" GFM rule. For a new paragraph, leave a blank line between blocks.

Raw HTML in my Markdown is getting escaped

If the converter is in "safe" mode, it HTML-escapes tags like `<iframe>` and `<script>` to prevent XSS. Toggle off safe mode only if you're the sole author of the input — never for user-submitted content.

Tables aren't rendering

Tables are a GitHub-Flavored Markdown extension, not part of CommonMark. Confirm the pipe `|` separators are on every row, including the divider `| --- |` line, and that there's a blank line before the table.

Code blocks render but without syntax colors

The converter outputs a `<code class="language-xxx">` hook — the actual highlighting is done by a JS library you include on the destination page (Prism, highlight.js, Shiki, etc.). Add the library and its CSS to the page where you paste the HTML.

Frequently Asked Questions

What Markdown features are supported?

Our converter supports the full CommonMark specification including headings (H1-H6), bold, italic, strikethrough, links, images, ordered and unordered lists, code blocks with syntax highlighting, tables, blockquotes, and horizontal rules.
