Welcome to the Markdown Editor. This tool lets you:
Use **bold** and *italic* for emphasis. Add links like this.
Blockquotes are great for pull quotes or callouts.
Add ``code blocks`` for snippets.
Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write formatted text using plain-text syntax that's easy to read and write. Markdown is used everywhere — GitHub READMEs, documentation sites, blog posts, note-taking apps, and static site generators like Astro, Hugo, and Jekyll.
A live-preview Markdown editor helps you write faster by showing you the rendered output as you type. You can catch formatting mistakes immediately, experiment with syntax, and copy the final HTML for use in any web project. Our editor supports headings, bold, italic, links, code blocks, lists, blockquotes, and horizontal rules.
Use # through ###### for headings. Wrap text in**double asterisks** for bold, *single asterisks* for italic. Create links with [text](url). Start lines with - for unordered lists or 1. for ordered lists. Use triple backticks for code blocks and single backticks for inline code.

No. This Markdown editor runs entirely in your browser. Nothing you type is sent to a server or stored anywhere outside your device. You can use it safely for private notes and proprietary documentation.
The editor supports standard CommonMark syntax including headings, bold, italic, links, images, ordered and unordered lists, code blocks, inline code, blockquotes, and horizontal rules. It covers the syntax used by GitHub, GitLab, and most documentation platforms.
Absolutely. The split-view layout works well for longer documents. Write your content in the left panel and scroll through the preview on the right to verify formatting. When you're done, copy the HTML and paste it into your web application or CMS.
