About Online Markdown Editor and Preview

Markdown has become the default format for a lot of technical and web writing — READMEs, documentation, forum posts — because it’s plain text that becomes properly formatted text with minimal syntax to remember.

This tool shows a live preview as you type, so you can see exactly how headers, lists, bold text, and links will actually render before pasting the result somewhere else that supports Markdown.

Useful for drafting content meant for a platform that renders Markdown (GitHub, many documentation tools, some blogging platforms) without needing to guess at syntax or preview separately after the fact.

Frequently Asked Questions

What is Markdown?

Markdown is a lightweight way to format text using plain characters, such as # for headings, asterisks for bold and italics, and hyphens for lists. A converter turns it into HTML. It is widely used for documentation, README files, notes and blog posts.

What is a Markdown file?

A Markdown file is a plain text file, usually ending in .md, that contains Markdown formatting symbols. Any text editor can open it. Paste its contents into the left pane here to see the formatted result on the right.

What is Markdown syntax?

The basics are # at the start of a line for headings, double asterisks around text for bold, single asterisks for italics, a hyphen at the start of a line for bullet lists, and [label](url) for links. The editor loads a sample using several of these so you can edit it and watch the preview change.

How do I preview Markdown in the browser?

Type or paste Markdown into the left box and the formatted preview updates on the right after a short pause. Nothing is installed or saved, so copy your text before closing the tab. Use Copy HTML or Download .html to take the rendered result with you.
