Frequently asked questions
Is my Markdown uploaded to a server?
No. The entire conversion runs locally in your browser using client-side JavaScript. Your Markdown and the generated HTML never leave your device and are never sent to or stored on any server, so it's safe for private notes, drafts, and internal docs.
Which Markdown features are supported?
It covers a focused, safe subset: headings (# through ######), bold (**text**), italic (*text*), inline code (`code`), unordered (- or *) and ordered (1.) lists, links, paragraphs, and line breaks. This keeps the output predictable and clean for pasting into emails, CMS fields, or web pages.
Is the generated HTML safe from script injection?
Yes. The input is fully HTML-escaped first, so no raw user markup can reach the output, and links are restricted to http(s) and relative URLs (schemes like javascript: are rendered as plain text). Only a whitelist of formatting tags is emitted, making the result deterministic and injection-safe.
