Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language created by John Gruber. It uses plain text formatting (like # for headings, ** for bold) that converts to HTML. Used widely on GitHub, Stack Overflow, and in documentation.
Which Markdown standard does this use?
This tool uses CommonMark, the standardized Markdown specification that ensures consistent rendering across platforms.
Can I use HTML inside Markdown?
Yes. Most Markdown processors allow inline HTML, so you can mix Markdown syntax with HTML tags for more complex formatting.
Does it support code syntax highlighting?
This tool renders fenced code blocks with language annotations. The preview shows the code formatted in a monospace font.
