Frequently Asked Questions
What is markdown?
Markdown is a lightweight markup language that allows you to format text using simple, readable syntax. It converts to HTML and is widely used on GitHub, Reddit, Stack Overflow, and many documentation platforms.
How does the live preview work?
As you type in the markdown editor, our tool instantly converts your markdown to HTML and displays it in the preview pane. There's no delay - it updates in real-time with every keystroke.
Can I copy the HTML output?
Yes! Click the "Copy HTML" button to copy the converted HTML to your clipboard. You can then paste it into any HTML editor, CMS, or web page.
Does this support all markdown syntax?
Yes, we support standard markdown syntax including headers, bold, italic, lists, links, images, code blocks, blockquotes, tables, and more. We use the Marked.js library which supports CommonMark and GitHub Flavored Markdown.
Is my markdown content saved?
No, your content is only stored in your browser while you're editing. When you close the page, it's gone. For privacy and security, we don't save or upload your content to any server.
Can I use this for GitHub README files?
Absolutely! This editor supports GitHub Flavored Markdown, so it's perfect for previewing README files, issue comments, pull request descriptions, and any other GitHub markdown content.
Does it work offline?
The initial page load requires internet to load the libraries, but once loaded, the markdown-to-HTML conversion happens entirely in your browser and works offline.
Can I export my work?
Yes! You can copy the markdown, copy the HTML, or download the HTML as a .html file. Multiple export options give you flexibility in how you use your content.
What programming languages are supported in code blocks?
Code blocks support syntax specification (e.g., ```javascript), though the current version displays them with monospace formatting. All major languages like JavaScript, Python, Java, C++, HTML, CSS, and more are recognized.
Is this better than other markdown editors?
Our editor focuses on simplicity and speed. It provides instant real-time preview, works in your browser without installation, has no sign-up requirements, and is completely free. Perfect for quick markdown editing and previewing.
