Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language with plain-text-formatting syntax. It is designed so that it can be converted to HTML and many other formats using a tool which shares the same name.
Are my documents private?
Absolutely. All parsing, rendering, and downloading are performed locally within your browser tab. No document content is ever sent to a server, keeping your data 100% private.
How do I insert formatted elements?
You can write standard Markdown syntax manually, or use the quick toolbar above the input box to automatically wrap selected text in formatting symbols like bold, headers, list tokens, or blockquotes.
Is the HTML output clean?
Yes. The tool compiles your Markdown into standard, semantic HTML elements, which are purified using DOMPurify before rendering to prevent malicious scripting injections.
