Markdown Editor

Write Markdown on the left, see the live preview on the right.

Write Markdown with a live preview

The Markdown Editor lets you write in Markdown on the left and see the formatted result render instantly on the right. Markdown is a lightweight syntax for formatting plain text using simple symbols, such as asterisks for bold, underscores for italics, and hash signs for headings. It is the standard for README files, documentation, GitHub comments, static-site blog posts, and many note-taking apps.

This editor is for writers, developers, and students who want to draft formatted content quickly without wrestling with a heavy word processor. The split-screen layout means you never have to guess how your syntax will look, because the rendered HTML preview tracks your typing in real time.

How to use the editor

Start typing in the left-hand pane, or use the toolbar buttons to insert formatting around your selection: B for bold, I for italic, H for a heading, the code button for inline code, the link button to insert a link, and the list button for bullet points. Select some text first and the button wraps it; with nothing selected, it inserts the markers ready for you to type between them.

The right-hand pane shows the live preview. When you are happy with the result, use Copy MD to copy the raw Markdown source, or Copy HTML to copy the rendered HTML output for pasting into a website or email. The editor supports common Markdown features including headings, bold and italic text, lists, links, blockquotes, and fenced code blocks.

Safety and privacy

The preview is sanitised before it is displayed: script tags, inline event handlers, and javascript: links are stripped out, so pasted Markdown cannot run malicious code in the preview pane. This keeps the editor safe to use even when you paste content from an unknown source.

Everything happens locally in your browser. Your Markdown is never uploaded to a server or saved anywhere outside your own device, and the tool is completely free with no account required. Note that content is held in memory only, so copy or save your work before closing the tab.
