What is the Markdown Editor?
A Markdown editor lets you write formatted text using a simple plain-text syntax (**bold**, # Heading, [link](url)) and renders it to HTML in real time. Markdown was created by John Gruber in 2004, and now powers GitHub READMEs, static site generators, Discord and Slack messages, and most modern documentation systems.
How to use the Markdown Editor
- 1
Write Markdown on the left
The editor starts with a sample document showing every supported syntax. Replace it with your own.
- 2
Watch the preview render on the right
The right pane updates on every keystroke using the marked library, with DOMPurify sanitizing the output. Tables, code blocks, task lists, and blockquotes all work.
- 3
Copy the rendered HTML
Click Copy HTML to grab the rendered output. Paste straight into a CMS, email template, or any place that accepts HTML.
- 4
Or copy the source Markdown
The small icon above the editor copies the raw Markdown if that's what you need.
Frequently Asked Questions
What Markdown syntax is supported?
Full GitHub Flavored Markdown via the marked library: headings (H1-H6), bold and italic, links and images, ordered and unordered lists, fenced code blocks with language tags, tables, blockquotes, horizontal rules, and inline code. Soft line breaks render as <br> (the breaks: true option), matching GitHub's behavior.
Can I copy the rendered HTML?
Yes. The Copy HTML button puts the sanitized rendered HTML on your clipboard. The output runs through DOMPurify before you see it, so you don't accidentally copy a <script> tag if your Markdown happened to embed one.
Is my content saved?
Nothing is saved or transmitted. The editor lives entirely in your browser; close the tab and everything you typed is gone. Copy your Markdown out before you leave if you want to keep it.
