Frequently Asked Questions (FAQ)
Q: Is my markdown content sent to any server?
A: No, all conversion and sanitization happen locally in your web browser. Your draft text is 100% private and secure.
Q: What security measures are implemented here?
A: The tool utilizes the marked parser combined with the DOMPurify library. This sanitizes the generated HTML, removing any script tags or malicious payloads (preventing XSS attacks) before previewing or copying.
