Understanding Markdown

Markdown has become the de facto standard for writing formatted content on the web. Created by John Gruber in 2004, it was designed so that plain text documents would be readable as-is while also being convertible to valid HTML. Today, Markdown is used on GitHub, Stack Overflow, Reddit, Notion, and thousands of other platforms. Its simplicity makes it accessible to non-technical users while remaining powerful enough for developers writing documentation.

Markdown Syntax Quick Reference

Headings use hash symbols: # H1, ## H2, through ###### H6. Bold text is wrapped in double asterisks **bold**, and italic text uses single asterisks *italic*. Links follow the pattern [text](url). Code can be inline with backticks or in fenced blocks with triple backticks. Lists use - or * for unordered and numbers for ordered. Blockquotes start with >.

Why Use a Live Preview Editor?

Writing Markdown without preview means guessing how your formatting looks until you render it. A live preview editor removes that friction — you see the result as you type. This is especially useful when writing README files, blog posts, or documentation. Need to check the character count of your text? Try our character counter.

Frequently Asked Questions

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It lets you write formatted text using simple syntax like # for headings, ** for bold, and * for italic. Markdown files are plain text and can be converted to HTML, PDF, and other formats.

What Markdown features does this editor support?

Can I copy the generated HTML?

Yes. Click the Copy HTML button to copy the raw HTML output to your clipboard. You can then paste it into your website, CMS, or any HTML editor.
