Frequently Asked Questions

What is Markdown?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax that is easy to read and write, and converts to HTML. Common syntax includes # for headings, ** for bold, * for italic, - for lists, and [text](url) for links. Markdown is used in GitHub, Reddit, Notion, and many documentation systems.
What Markdown features does this converter support?
This converter supports headings (h1-h6), bold (**text**), italic (*text*), links ([text](url)), images (![alt](url)), unordered lists (- item), ordered lists (1. item), code blocks (```), inline code (`code`), blockquotes (> text), horizontal rules (---), and tables (| col | col |).
Is this converter secure?
This converter runs entirely in your browser. No data is sent to any server. The conversion happens client-side using JavaScript. However, the HTML output should be sanitized before injecting into a webpage to prevent XSS attacks if the Markdown source is untrusted.
Can I use the generated HTML on my website?
Yes. The generated HTML is standard and can be used in any website or application. Copy the raw HTML output and paste it into your codebase. You may want to add CSS styling since the output is unstyled semantic HTML. Most CSS frameworks and CMS systems style these elements by default.
What is the best way to learn Markdown?
Start with the basics: headings (#), bold (**), italic (*), links, and lists. These cover 90% of daily use. Practice on GitHub READMEs, Reddit comments, or a Markdown editor like Typora or VS Code. The full CommonMark spec at commonmark.org is the definitive reference for edge cases.
