Markdown Editor
Write and preview in real-time

❓ Frequently asked questions

What is Markdown and why should I use it?

Markdown is a lightweight markup language created in 2004 by John Gruber. It allows you to format text using a simple, readable syntax even without rendering (e.g., `**bold**` instead of complex HTML tags). It has become the standard for technical documentation (GitHub), blogs (Jekyll, Hugo), notes (Obsidian, Notion), and technical forum communication because it’s fast to write, easy to read, and portable across platforms.

Are my texts saved anywhere?

No. Everything you write stays exclusively in your browser. When you close the page, the content disappears. If you want to keep your work, use the “Download .md” button to save the file to your device. There is no server database storing your texts.

Can I use the editor offline?

Yes. After the first page load, the editor works completely offline. The Marked.js library and all scripts are loaded in the browser, so you can write and see the preview even without an internet connection. This makes it ideal for working while traveling or in places with limited connectivity.

What’s the difference between “Copy MD” and “Copy HTML”?

Copy MD copies the source text in Markdown syntax (e.g., `# Title`, `**bold**`). It’s useful for pasting into Markdown editors like Obsidian or GitHub. Copy HTML copies the rendered HTML code (e.g., `

What Markdown syntax is supported?

The editor supports standard Markdown syntax (CommonMark) plus GFM (GitHub Flavored Markdown) extensions. This includes: headings (h1-h6), bold/italic text, ordered and unordered lists, links, images, blockquotes, tables, code blocks with syntax highlighting, inline code, horizontal rules, and strikethrough. The initial guide text in the editor demonstrates all these features.

Can I use this editor to write WordPress articles?

Absolutely. Write your article in Markdown, then you have two options: use “Copy HTML” and paste into the WordPress block editor (switching to “Custom HTML” mode if necessary), or download the .md file and use a plugin like “WP Markdown Editor” to import it directly. Many bloggers and content creators use this workflow to write in cleaner environments than the native WordPress editor.

Why does the preview sometimes not exactly match GitHub?

The editor uses the Marked.js library which implements the CommonMark + GFM standard. GitHub uses a slightly customized version of Markdown with some proprietary extensions. In the vast majority of cases (99%) the result is identical. For small differences (like rendering of some complex tables or specific emoji), I recommend always doing a final test on GitHub before publishing critical documentation.
