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.

Q: Can I use standard HTML tags inside Markdown?

A: Yes, standard Markdown allows inline HTML. However, unsafe elements like script, iframe, or event handlers will be sanitized and removed for security.
