About Markdown Online

Markdown Online is a free, open-access Markdown editor built for writers, developers, students, and anyone who works with text. Our mission is simple: provide the fastest, most intuitive way to write and preview Markdown directly in your browser, with zero friction and zero cost.

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It allows you to write formatted text using a plain-text syntax that is easy to read and easy to write. Markdown is widely used for documentation, README files, blog posts, notes, and much more. It converts cleanly to HTML, making it a favorite among developers and technical writers worldwide.

Why Markdown Online?

There are many Markdown editors available, but most require you to download software, create an account, or pay for premium features. Markdown Online takes a different approach. Everything runs entirely in your browser. Your content never leaves your device. There are no servers processing your text, no accounts to manage, and no subscriptions to worry about. Just open the site and start writing.

Key Features

• Live Preview: See your Markdown rendered in real-time as you type. The split-pane layout shows your source on the left and the formatted output on the right.
• Toolbar Shortcuts: Quickly insert bold, italic, headings, links, images, code blocks, lists, and blockquotes with a single click.
• Export Options: Download your work as a .md file or export it as a fully styled HTML document. You can also copy raw Markdown or rendered HTML directly to your clipboard.
• Auto-Save: Your content is automatically saved to your browser's local storage every two seconds. Come back later and pick up right where you left off.
• Dark Mode: Toggle between light and dark themes to match your preference or system settings.
• Mobile Friendly: The responsive design adapts to any screen size, with a tabbed interface on smaller devices.

Privacy First

We believe your writing is your own. Markdown Online processes everything client-side. Your documents are stored only in your browser's local storage and are never transmitted to any server. We do not collect, store, or have access to any of your content. Read our Privacy Policy for more details.
