Markdown Preview & Markdown to HTML Converter

This free Markdown previewer renders Markdown as formatted HTML in real time as you type — headings, bold and italic text, lists, links, code blocks, tables, and blockquotes all appear instantly beside your source. You can also copy the generated HTML, making the tool a quick Markdown to HTML converter for blog posts, CMS content, and email templates.

Rendering happens locally in your browser using the CommonMark-compatible marked parser, and the preview is sanitized with DOMPurify so pasted content cannot run scripts. Your writing never leaves your device.

How to use Markdown Preview

  1. Type or paste Markdown into the left panel.
  2. Watch the rendered preview update live on the right.
  3. Press the copy button to copy the generated HTML for use in a CMS, blog engine, or email template.

Why Markdown?

Markdown lets you write structured documents in plain text: readable in its raw form, versionable in Git, and convertible to clean HTML. It has become the standard for README files, documentation sites, GitHub issues, and static site generators — and previewing while you write catches formatting mistakes (a missing blank line, an unclosed code fence) before you publish.

Related terminology

Markdown
A lightweight plain-text markup language created in 2004, designed to be readable as-is and convertible to HTML.
CommonMark / GFM
CommonMark is the standardized Markdown specification; GitHub Flavored Markdown (GFM) extends it with tables, task lists, and strikethrough.
Code fence
Triple backticks that open and close a code block, optionally tagged with a language name.
Sanitization
Filtering generated HTML to remove scripts and dangerous attributes before display — this preview sanitizes with DOMPurify.

Frequently asked questions

How do I convert Markdown to HTML?
Paste your Markdown into the editor and press the copy button next to the preview — the clipboard receives the generated HTML, ready for your CMS or template.
Which Markdown features are supported?
The standard CommonMark set: headings, emphasis, lists, links, images, blockquotes, inline code, and fenced code blocks, plus common extensions like tables.
Is the preview safe if I paste untrusted Markdown?
Yes. The rendered HTML is sanitized with DOMPurify before display, which strips script tags, event handlers, and other executable content.
Why does my list or code block render wrong?
The usual causes are a missing blank line before the list or fence, inconsistent indentation, or an unclosed ``` fence. The live preview makes these easy to spot and fix.
