About Markdown Previewer

The Markdown Preview tool is a live Markdown editor that renders formatted HTML in real time as you type. Paste or write Markdown on the left and watch the rendered preview update instantly on the right — no need to click a button or refresh anything.

It supports the Markdown syntax people actually use: headings, bold and italic text, strikethrough, links, images, ordered and unordered lists, blockquotes, inline code, fenced code blocks with language labels, horizontal rules, and GitHub-flavored tables.

Switch the right panel between a rendered Preview and the raw HTML Output to grab the generated markup directly — handy for pasting formatted text into emails, CMS fields, or static sites.

Everything runs locally in your browser using a lightweight built-in Markdown parser. Your text is never uploaded or stored on a server.

How to Use Markdown Previewer

  1. Type or paste Markdown into the left panel — a sample document is preloaded so you can see it in action.

  2. The rendered preview on the right updates instantly as you type.

  3. Toggle to 'HTML' to see and copy the generated HTML markup instead of the visual preview.

  4. Use Copy MD or Copy HTML to grab whichever version you need.

Frequently Asked Questions

Does this support GitHub Flavored Markdown (GFM)?

It supports the most commonly used GFM features: tables, strikethrough (~~text~~), fenced code blocks with language labels, and autolinks. It is not a full CommonMark/GFM implementation, but it covers what most people write day to day.

Can I copy the rendered output as HTML?

Yes — switch the right panel to 'HTML' and click 'Copy HTML' to copy the generated markup, ready to paste into a CMS, email client, or static site.

Is my Markdown uploaded anywhere?

No — parsing and rendering happen entirely in your browser using a built-in Markdown parser. Nothing is sent to a server.

How do I create a code block with syntax highlighting label?

Wrap your code in triple backticks and add a language name right after the opening fence, e.g. ```js — this adds a language-js class to the generated <code> element.

Does it support tables?

Yes — use standard GFM pipe-table syntax with a header row, a separator row (e.g. |---|:--:|--:|), and body rows. Left, center, and right alignment are all supported.

Why didn't my nested list render correctly?

This tool supports single-level lists with simple lazy-continuation lines. Deeply nested or multi-level lists may not render exactly as in a full Markdown processor.
