Frequently Asked Questions
What Markdown syntax is supported?
This tool uses the marked library, which supports standard CommonMark and GitHub Flavored Markdown (GFM) — including headings, bold, italic, links, images, lists, blockquotes, inline code, fenced code blocks, and tables.
Is the HTML output safe to use in production?
The raw HTML output is not sanitized, so user-provided Markdown could contain unsafe HTML. For production use, always sanitize the output with a library like DOMPurify before inserting it into the DOM.
What is the difference between Markdown and HTML?
Markdown is a lightweight plain-text format designed to be readable as-is and easily converted to HTML. HTML is the markup language rendered by browsers. Markdown is often used in documentation, README files, and content management systems where authors prefer a simpler syntax.
