TypeMD

TypeMD is a free, privacy-focused Markdown editor that runs entirely in your browser, storing all content locally via localStorage while showing a live HTML preview as you type.

What is TypeMD?

TypeMD is a free online Markdown editor that takes Markdown text as input and renders formatted HTML output in a real-time preview pane. The tool works in any modern web browser and requires no server-side processing or account creation. It was made by Kevin Barrionuevo and is hosted by Infomaniak, an environmentally friendly data center in Switzerland. All documents are stored locally on your device using the browser's localStorage, so nothing is ever uploaded.

Key Features

TypeMD provides a complete set of editing tools in a single browser tab, including a formatting toolbar, media insertion, themes, and export functions.

• Local-first storage — Every keystroke is saved to your browser's localStorage, so your documents persist between sessions without any cloud sync or login.
• Real-time preview — The preview pane updates instantly as you type, showing exactly how your Markdown will render.
• Formatting toolbar — A simple toolbar inserts Markdown syntax for headings, bold, italic, links, and more with one click.
• Media insertion — Insert images, links, and tables directly from the toolbar without hand-typing Markdown.
• Light and dark themes — Switch between a clean light theme and a dark theme to match your environment.
• Export to Markdown — Download your current document as a .md file to back it up or move it elsewhere.
• Source mode with preview — Work in source view while a separate preview pane shows the rendered output side by side.
• Syntax-highlighted code blocks — Code fences are highlighted for many programming languages, making the editor suitable for developer documentation.

Who is TypeMD for?

TypeMD is aimed at anyone who writes in Markdown and wants their content to remain on their own device.

• Bloggers — Draft blog posts in Markdown and export the file for publication on any static-site generator or CMS.
• Developers — Write project documentation with syntax-highlighted code blocks, all stored locally.
• Students — Take class notes in a distraction-free editor without creating an account or worrying about data leaving the device.
• Privacy-conscious writers — Keep sensitive drafts entirely on your own machine, with no content ever sent to a server.

What can you do with TypeMD?

TypeMD lets you handle a range of writing tasks entirely in the browser, from article drafting to code documentation.

• Draft and export blog posts: Write a full article in Markdown, preview it live, then click export to get a .md file ready for your publishing workflow.
• Document code projects: Create README files or API docs with fenced code blocks that get syntax highlighting in the preview.
• Take private notes: Because content never leaves the browser, you can use TypeMD for journaling or note-taking that stays on your device.
• Learn Markdown: The instant preview makes it easy to experiment with syntax and see what each symbol does.

How does TypeMD work?

Open the site, start typing in the editor, and the preview pane updates in real time. Everything is automatically saved to your browser's localStorage as you type. To keep a permanent copy, click the export button to download your document as a Markdown file. That's the entire workflow — no sign-up, no setup, just open and write.

Pros and cons

TypeMD's main strength is its local-first privacy approach, while its main drawback is dependence on browser storage.

• Pros: Complete privacy (no data sent to servers), no registration required, real-time preview, export capability, and a clean interface.
• Cons: Because data lives only in localStorage, clearing your browser data removes all saved documents — the page explicitly warns to export your work before clearing browser data.

Pricing

TypeMD is free to use for everyone. There are no paid tiers, subscriptions, or hidden costs.

FAQ

Is my data secure?

Yes. All content is stored locally in your browser using localStorage. TypeMD never sends your data to any server, so it cannot be intercepted or viewed by anyone else.

Do I need to create an account?

No account is necessary. TypeMD works immediately when you open the website — there is no sign-up or login process.

What happens if I clear my browser’s data?

Clearing your browser's data removes all documents you've saved in TypeMD, because they're stored in localStorage. Make sure to export your work as a Markdown file before clearing your browser data.

Can I export my work?

Yes. TypeMD includes an export feature that downloads your current document as a .md file, so you can back it up or use it elsewhere.
