Markdown Editor & Preview

Markdown powers README files, documentation, notes, blogs and half the comments on the internet, because it lets you format text as fast as you can type. Our free Markdown editor pairs a writing pane with a live preview, so you see headings, lists, links, code blocks, quotes and tables exactly as they will render while you write. When your document is ready, copy the Markdown or the generated HTML for your site. Everything runs in your browser, so drafts are private and there is nothing to install or sign up for.

Quick Answer: Type Markdown in the left pane and the formatted result appears instantly on the right. Headings, bold, lists, links, images, code, quotes and tables are all supported.

How to Use the Markdown Editor & Preview

  1. Start typing in the editor pane; the sample text shows the most useful syntax if you are new to Markdown.
  2. Watch the preview update with every keystroke to confirm your formatting renders as intended.
  3. Use the toolbar buttons to insert common elements like headings, bold text, links and code blocks.
  4. Check the word and character counts under the editor if your document has length requirements.
  5. Copy the Markdown for platforms that accept it, or copy the generated HTML for a CMS or email tool.

Key Features

  • True live preview with no refresh, rendered by a hand-written parser on this page.
  • Supports headings, bold, italic, strikethrough, inline code and fenced code blocks.
  • Lists (bulleted, numbered and nested), blockquotes, horizontal rules, links, images and pipe tables.
  • Toolbar shortcuts for the elements beginners forget how to write.
  • One-click copy of either the raw Markdown or the rendered HTML.

Best Practices and Tips

  • Leave a blank line between blocks; most Markdown quirks come from paragraphs, lists and headings crowding each other.
  • Preview tables carefully: a missing pipe at a row’s end is the usual reason a table renders as plain text.
  • For documentation, keep one idea per heading and use descriptive link text instead of raw URLs, which reads better in every renderer.
  • Remember flavours differ slightly (GitHub, GitLab, Reddit); test critical documents on the destination platform before a big publish.

Common Mistakes to Avoid

  • Expecting HTML styling inside Markdown to survive everywhere; many platforms strip embedded HTML for safety, so rely on Markdown syntax itself.
  • Using spaces inconsistently for nested lists; two or four spaces before a sub-item must be consistent within one list.
  • Writing reference-style links in editors that only support inline links, then wondering why they appear as plain text.

Frequently Asked Questions

What is Markdown used for?

Markdown is a lightweight way to format plain text, created so the source stays readable. It is used for GitHub READMEs, documentation, static site blogs, note-taking apps, forums and technical writing of every kind.

Which Markdown features does this editor support?

Headings levels 1 to 6, paragraphs, bold, italic, strikethrough, inline code, fenced code blocks with optional language label, bullet and numbered lists including one level of nesting, blockquotes, links, images, horizontal rules and simple pipe tables.

Can I export my document as HTML?

Yes. The Copy HTML button places the rendered HTML on your clipboard, ready to paste into a web page, CMS or email builder. The HTML is clean semantic markup generated from your Markdown.

Is my writing saved anywhere?

No. The document exists only in your browser tab. If you close or reload the page, the text is gone, so copy important drafts into your own files or notes app as you work.

Why does my table not render?

Tables need a header row, a separator row of dashes and pipes (like | — | — |), and the same number of columns in every row. Check for a missing trailing pipe; it is the most frequent cause.
