What Is Markdown Preview?

Markdown — first created by John Gruber — is plain text with syntax for headings, lists, and links. Markdown Preview lets you write and see the rendered HTML live. The CommonMark spec defines the standard syntax; rendering is powered by marked.js.

This tool runs entirely in your browser. Nothing is sent to a server. Copy HTML or download for use elsewhere. For formatting Markdown, use Markdown Formatter. For conversion only, use Markdown to HTML.

How to Use This Tool

Paste or Upload

Copy your Markdown and paste it into the left editor. You can also click Upload to load a .md or .markdown file. The Sample button loads example data.

Check the Live Preview

The right panel shows the rendered HTML. Edit on the left; the preview updates in real time. Use Copy HTML or Download HTML to get the output.

Copy or Download

Use Copy HTML or Download HTML to get the rendered output. For formatting or validation, use the Markdown Formatter or Markdown Validator.

When Markdown Preview Helps

When writing docs, READMEs for GitHub, or content and you want instant feedback, the live preview shows exactly how it will render. The GFM spec defines tables and task lists. Great for Jekyll, Hugo, or documentation. For a full editor with download options, use the Markdown Editor.

Frequently Asked Questions

What does "rendering" Markdown actually mean?

Rendering converts the plain-text Markdown syntax — like **bold** or # Heading — into proper HTML elements like <strong> and <h1>. This tool renders your Markdown in real time so you can see exactly how it will look when published.

Which Markdown specification does this tool follow?

The preview follows the CommonMark spec, which is the most widely adopted standard for Markdown. It also supports GitHub Flavored Markdown (GFM) extensions including tables, task lists, and strikethrough.

Can I use this to preview README files?

Absolutely. Paste your README Markdown into the editor and the preview will show you how it renders — including GFM tables and task lists that GitHub uses. It's a quick way to catch formatting issues before you commit.

Is my content sent to a server?

No — everything runs locally in your browser. Your Markdown never leaves your machine. There are no uploads, no accounts, and no tracking. It's completely private.

What about raw HTML?

Raw HTML in Markdown is typically passed through to the preview. For converting HTML to Markdown, use HTML to Markdown.
