Markdown to HTML Converter

Q: How do I convert Markdown to HTML?

Paste your Markdown into the left pane of this converter. The HTML appears on the right immediately, already indented. Copy it or download it as a .html file.

Q: Is this Markdown to HTML converter free?

Yes. It is free, needs no account and has no limits on document size beyond what your browser can hold.

Q: Is my Markdown uploaded to a server?

No. The conversion happens in your browser with JavaScript. Your text never leaves the device, and the only copy stored is the draft in your own browser storage.

Q: What is the difference between a fragment and a full document?

A fragment is just the body markup — headings, paragraphs and lists — meant to be pasted inside a page you already have. A full document adds the doctype, head, meta tags, a title and basic styling so the file opens correctly on its own.

Q: Can I get minified HTML?

Yes. Choose Minified as the output mode and the whitespace between tags is removed. Code blocks keep their exact formatting, because whitespace is significant inside a pre element.

Q: Does the converter support tables?

Yes. GitHub-style pipe tables convert to a real table element, and the alignment row with colons becomes text-align styling on each cell.

Q: Is raw HTML in my Markdown passed through?

No. Raw HTML is escaped and appears as literal text in the output. This keeps the converter safe for Markdown from untrusted sources, since pasted script tags cannot run.

Q: Can I add id anchors to headings?

Yes. Turn on Heading ids and every heading gets a slug id, such as id="getting-started", so you can link directly to a section. Duplicate headings get a numeric suffix to stay unique.

Q: Can I make links open in a new tab?

Yes. Turn on target=_blank and every link gets target and a rel of noopener noreferrer. Leave it off for the cleanest possible markup.

Paste Markdown, take away clean HTML. Choose a pretty-printed fragment, a complete HTML document or minified output — then copy it or download the file.

What is this tool?

This Markdown to HTML converter turns Markdown into clean, semantic HTML you can paste straight into a website, a CMS field or a template. It parses GitHub-flavored Markdown — headings, lists, tables, task lists, fenced code, blockquotes and links — and pretty-prints the result with the indentation you choose.

Conversion happens in your browser. Nothing is uploaded, and raw HTML in your source is escaped rather than passed through, so a Markdown file from an untrusted source cannot inject scripts into the output.

Which output mode should you pick?

The three modes produce the same markup — they differ in what wraps it and how it is spaced.

HTML fragment Just the body markup, indented and readable. Use this when you are pasting into a page, a CMS block or a component that already has its own head and styling.

Full HTML document Adds the doctype, head, charset, viewport, a title taken from your first heading, and basic styling. The file opens correctly on its own — good for sharing or archiving.

Minified Whitespace between tags removed for the smallest payload. Code blocks keep their exact formatting, because whitespace is meaningful inside <pre>.

What each Markdown construct becomes

The exact HTML this converter emits. Paste any of the left column into the editor to see it.

Markdown	HTML output	Notes
# Title	<h1>Title</h1>	Six levels. Turn on Heading ids to add slug anchors.
Title =====	<h1>Title</h1>	Setext headings work too; `-----` gives an h2.
bold	<strong>bold</strong>	Semantic emphasis, not `<b>`.
_italic_	<em>italic</em>	Semantic emphasis, not `<i>`.
~~struck~~	<del>struck</del>	GitHub-flavored extension.
==marked==	<mark>marked</mark>	Highlight extension.
`code`	<code>code</code>	Contents are escaped and never re-parsed.
```js … ```	<pre><code class="language-js">…</code></pre>	The `language-` class is what highlighters look for.
> quote	<blockquote><p>quote</p></blockquote>	Nests when you repeat `>`.
- item	<ul><li>item</li></ul>	Indent two spaces to nest a sublist.
1. item	<ol><li>item</li></ol>	A different starting number becomes `start="n"`.
- [x] done	<li><input type="checkbox" disabled checked />…	Checkboxes are disabled, as on GitHub.
[text](url)	<a href="url">text</a>	Add target and rel with the option above.
![alt](url)	<img src="url" alt="alt" />	Optionally adds `loading="lazy"`.
\| a \| b \|	<table><thead>…</thead><tbody>…	The `:---:` row becomes `style="text-align:…"`.
---	<hr />	Three or more dashes, asterisks or underscores.
<div>raw</div>	<div>raw</div>	Raw HTML is escaped on purpose — see the safety note below.

How Markdown becomes HTML

A Markdown converter works in two passes. The block pass reads the document line by line and decides what each chunk is: a heading, a list, a table, a fenced code block, a paragraph. The inline pass then walks the text inside each block and handles the finer marks — bold, italic, links, code spans.

Order matters. Fenced code is lifted out before anything else runs, otherwise a # or * inside a code sample would be treated as syntax. Inline code spans are pulled out for the same reason. Only then is the remaining text escaped and the tags built around it.

Why the output is escaped

Some converters pass raw HTML through untouched. That is convenient, and it is also how a malicious Markdown file can run script in whatever page embeds the result. This converter escapes raw HTML and checks every link and image destination against an allow-list of URL schemes, so javascript: and data:text/html destinations never reach the output.

Where the HTML goes next

A CMS or WordPress: use the fragment mode and paste into a custom HTML block.
A static site: paste the fragment into a template partial, or take the full document and style it yourself.
Documentation: turn on heading ids so your sidebar or table of contents can link to sections.
A README rendered on your own site: fragment mode plus your existing stylesheet.
Email: treat the output as the content layer — email clients still need inline styles on top.

Converter or previewer?

Use this page when the HTML is the deliverable — you want the code, formatted the way you like, ready to paste. Use the Markdown Live Previewer when the document is the deliverable and you want to draft it, navigate it with an outline and check the reading time.

Both run entirely in the browser and share the same parser and the same safety rules.

Frequently asked questions

How do I convert Markdown to HTML?

Is this Markdown to HTML converter free?

Yes. It is free, needs no account and has no limits beyond what your browser can hold.

No. Conversion happens in your browser. Your text never leaves the device, and the only copy stored is the draft in your own browser storage.

What is the difference between a fragment and a full document?

A fragment is just the body markup, meant to be pasted inside a page you already have. A full document adds the doctype, head, meta tags, a title and basic styling so the file opens correctly on its own.

Can I get minified HTML?

Yes. Choose Minified and the whitespace between tags is removed. Code blocks keep their exact formatting, because whitespace is significant inside <pre>.

Does the converter support tables?

Yes. Pipe tables become a real <table>, and the alignment row with colons becomes text-align styling on each cell.

What Markdown syntax is supported?

Headings, paragraphs, bold, italic, strikethrough, highlight, inline code, fenced code blocks with a language class, blockquotes, GitHub alerts, nested lists, task lists, tables, horizontal rules, links, reference links, images, autolinks and hard line breaks.

Is raw HTML in my Markdown passed through?

No. Raw HTML is escaped and appears as literal text. This keeps the converter safe for Markdown from untrusted sources, since pasted script tags cannot run.

Can I add id anchors to headings?

Yes. Turn on Heading ids and every heading gets a slug id such as id="getting-started". Duplicate headings get a numeric suffix so ids stay unique.

Can I make links open in a new tab?

Yes. Turn on target="_blank" and every link also gets rel="noopener noreferrer". Leave it off for the cleanest markup.

How do I control indentation?

Pick two spaces, four spaces or tabs. Block elements go on their own lines and nested elements are indented, while inline content such as bold text and links stays on one line.

Can I convert a .md file?

Yes. Press Import to choose a file, or drag a .md file onto the workspace. The file is read locally and never uploaded.

Can I paste the output into WordPress or a CMS?

Yes. Use fragment mode and paste into a custom HTML block or a raw HTML field. Turn heading ids on if your theme builds a table of contents from them.

Can I use the output in an email template?

The markup is clean and semantic, which is a good starting point, but email clients need inline styles and often table-based layouts. Treat the output as the content layer and add email-specific styling on top.

What is the difference between this and the Markdown Live Previewer?

This page is aimed at the HTML you take away: output modes, indentation, anchors, copy and download. The Markdown Live Previewer is a writing environment for drafting and reading, with an outline and reading time.

Does it work offline?

Yes. Once the page has loaded, no network connection is needed to convert, copy or download.

Is the generated HTML valid?

The converter emits well-formed, semantic elements. Void elements are self-closed and attribute values are escaped, so the result validates as HTML5.

What happens to code blocks?

A fenced code block becomes a <pre> wrapping a <code>. A language after the opening fence becomes a language- class, which is what syntax highlighters expect.

Does it handle nested lists?

Yes. Indent a list item by two spaces to nest it, and the converter produces properly nested ul or ol elements inside the parent list item.

Can I convert HTML back to Markdown?

Not with this tool — it converts one way. Converting arbitrary HTML back to Markdown is a lossier problem, since HTML can express structures Markdown has no syntax for.
