How to use Markdown Preview

Preview a lightweight Markdown subset: headings, paragraphs, emphasis, strikethrough, code, flat lists, blockquotes, horizontal rules and links.

Details and limits

Raw HTML is displayed as text. Links allow only absolute HTTP, HTTPS and mailto addresses. Images, tables, nested lists, reference links and full CommonMark compatibility are not supported. Input is limited to 50,000 characters.

Practical example

Use this preview for simple Markdown drafts. Tables, images and nested lists are not supported, so it should not be used to check full CommonMark compatibility.

Enter # Project notes on one line and **Ready** in a separate paragraph. The preview shows a heading and bold text.

Frequently asked questions

What is the difference between the two copy actions?

Copying Markdown keeps the source syntax. Copying plain text uses the rendered preview's visible text rather than an HTML export.

Why does indentation disappear inside a normal paragraph?

Normal paragraphs follow the browser's whitespace rendering rules. Use a fenced code block when exact spacing and line breaks matter.

Will a language label add syntax highlighting to code?

No. Fenced code is shown as plain code text; a label such as javascript does not activate a highlighting engine.
