Markdown to HTML

What is the Markdown to HTML converter?

The Markdown to HTML converter is a free online tool that turns plain Markdown into clean, valid HTML. You write or paste Markdown on one side and instantly see two things: a live preview of how the page will render, and the raw HTML source you can copy or download. Markdown is a lightweight way to format text with simple symbols — a hash for a heading, asterisks for emphasis, dashes for a list — and this tool translates those symbols into the HTML tags a browser actually understands. It is built for the moment you have finished writing in Markdown and now need real HTML to drop into a website, blog post, email template, or documentation page.

How to use it

1. Type or paste your Markdown into the input box on the left.
2. The converter parses it as you type — the live preview and the HTML source both update immediately.
3. Toggle line breaks on if you want every single newline to become a <br> tag, which is handy for pasting prose written with hard returns.
4. Click Copy HTML to grab the source for your clipboard, or click Download .html to save it as a ready-to-open file.
5. Done — no account, no upload, no waiting.

The whole flow is designed so you get your HTML in one second and move on.

The method behind it

Under the hood the tool uses the mature, open-source marked parser to read your Markdown and emit standards-compliant HTML. Parsing happens synchronously in your browser, which is why the result appears the instant you stop typing. The live preview is an extra safety step: before any converted HTML is shown on screen, it is passed through DOMPurify, a widely used sanitizer that strips out script tags, inline event handlers, and dangerous URLs. That means even if your Markdown contains raw HTML, the preview cannot run a malicious script against your browser. The HTML source you copy is the parser's direct output, so it is faithful to your Markdown; if you intend to publish content from untrusted authors, sanitize it again on your own server before it goes live.

Examples

Convert a README heading and list

Input:

# Project Setup
1. Clone the repo
2. Run `npm install`

Output: an <h1> followed by an ordered list with two <li> items, the second containing an inline <code> element.

Turn a table into HTML

A pipe-delimited Markdown table becomes a full <table> with <thead> and <tbody> sections, ready to style with your own CSS.

Common use cases

• Publishing to a CMS — write a post in Markdown, then paste the generated HTML into WordPress, Ghost, or a custom editor.
• Email templates — convert formatted Markdown into the HTML that newsletters and transactional emails require.
• Documentation — preview a README or docs page exactly as it will render, then export the HTML.
• Static sites — drop the converted HTML straight into a page or component.
• Learning HTML — see precisely which tags each Markdown symbol produces.

Why use this one

Many converters show you either a preview or a blob of source code, but not both at once. This tool shows the rendered preview and the raw HTML together, with one-click copy and one-click download. More importantly, everything runs entirely in your browser, so your Markdown never touches a server — which matters when your draft is an unpublished article, an internal document, or anything you would rather not upload. It is fast, works on mobile, and needs no signup. When you need to go the other way, use the HTML to Markdown converter; to compare two drafts, try the Text Diff Checker; and to fill a layout with sample copy, grab some Lorem Ipsum.
