What is Markdown? Complete Guide to Lightweight Markup Language
Markdown is a lightweight markup language created by John Gruber in 2004 that revolutionized how developers and technical writers format text. Unlike bloated word processors or complex HTML editors, markdown uses intuitive plain-text formatting that converts seamlessly to clean, semantic HTML—making it the industry standard for README files, documentation, and technical content across GitHub, GitLab, Stack Overflow, and Reddit.
Our free online markdown editor eliminates formatting guesswork by providing instant visual feedback as you type. Watch your markdown syntax transform into beautifully rendered HTML in real-time, with professional Dracula theme syntax highlighting for code blocks supporting JavaScript, Python, Go, Rust, and 15+ programming languages. Perfect for developers writing API documentation, README files, or technical specifications.
Whether you're creating markdown documentation, writing blog posts for static site generators like Hugo or Jekyll, or formatting messages for Slack and Discord, this markdown to HTML converter ensures pixel-perfect output every time.

Frequently Asked Questions (FAQ) - Markdown Editor
Is this markdown editor completely free to use online?
Yes, our markdown to HTML converter is 100% free with no hidden costs, usage limits, premium tiers, or feature locks. All functionality—including syntax highlighting, live preview, GFM support, and markdown copying—is available to every user without registration. We believe developer tools should be accessible to everyone.
How does live markdown preview work technically?
Our editor uses Goldmark, a high-performance markdown parser written in Go, to convert markdown to HTML instantly as you type. The parsing happens client-side in your browser with sub-100ms latency, providing real-time visual feedback. We use Chroma for syntax highlighting and support the full CommonMark specification plus GitHub extensions.
Does the markdown editor work offline without internet?
Yes, once the page loads, all markdown processing happens locally in your browser using JavaScript. You can disconnect from the internet and continue writing and previewing markdown. Your content never touches our servers—it exists only in your browser's memory, ensuring complete privacy for confidential documentation.
What programming languages support syntax highlighting?
We support syntax highlighting for 15+ programming languages: JavaScript, TypeScript, Python, Go, Rust, Java, C, C++, C#, PHP, Ruby, Swift, Kotlin, Shell/Bash, and Markdown itself. Simply use fenced code blocks with language identifiers (```javascript, ```python, etc.) and get automatic Dracula-themed syntax coloring.
How do I convert markdown to HTML for my website?
Type or paste your markdown into the left editor panel and see the HTML output instantly in the preview pane. Click "Copy Markdown" to copy your formatted text. For clean HTML conversion, you can also export the rendered HTML. Need to work with other formats? Try our JSON formatter or XML formatter tools.
Can I use this for GitHub README files?
Absolutely! Our editor is specifically designed for GitHub Flavored Markdown. Write your README.md, see exactly how it will render on GitHub (including tables, task lists, code blocks, and links), then copy it directly to your repository. Perfect for testing markdown before committing to version control.
Is my markdown content saved automatically?
For privacy and security, we don't save your content on any servers. Your markdown exists only in your browser session. We recommend copying important content to your local machine or encrypting files before storing them. This ensures your proprietary documentation and sensitive information remain completely private.
