Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language that uses plain text formatting syntax. It was created by John Gruber in 2004 to make writing for the web easier. Markdown is widely used for README files, documentation, blog posts, and forum comments.
What Markdown features are supported?
This tool supports standard Markdown: headings, bold/italic, links, images, lists, code blocks, blockquotes, tables, and horizontal rules. It uses a simple regex-based parser, so complex extensions like footnotes or task lists may not render perfectly.
Can I use this for writing blog posts?
Yes! Write your content in Markdown, preview it here, then copy the HTML output or paste the Markdown into your CMS. Many blogging platforms (Ghost, Jekyll, Hugo) support Markdown natively.
