Why Use MDForge for Markdown Previews?

Unlike conventional preview tools that send your text to third-party rendering APIs, MDForge performs 100% of its Markdown parsing and HTML sanitization locally inside your browser. This ensures maximum speed, complete privacy, and zero data leakage.

Frequently Asked Questions

How fast is the Markdown preview?

The preview updates synchronously with sub-millisecond latency as you type in your browser.

Is the HTML sanitized to prevent malicious scripts?

Yes. All rendered output is purified through DOMPurify to strip dangerous JavaScript, tracking pixels, and unauthorized iframe tags.
