Markdown Syntax Reference
What is Markdown?
Markdown was created by John Gruber in 2004 as a lightweight plain-text format that converts to HTML. It is designed to be readable as-is, so you can write # Heading or **bold** without it looking like markup. Today Markdown is used in GitHub READMEs, blog platforms, documentation sites, and messaging apps worldwide.
Supported syntax
This converter supports the full CommonMark spec via marked.js: headings (#, ##, ###), bold (**text**), italic (*text*), inline code (`code`), fenced code blocks (```), unordered and ordered lists, links ([label](url)), images, blockquotes (>), horizontal rules (---), and pipe tables. The live preview renders the HTML exactly as a browser would display it.
When to use HTML output
Copy the HTML output when you need to paste formatted content into a CMS, email template, or any system that accepts raw HTML but not Markdown. The output is clean and minimal — no extra wrapper divs or inline styles — so it integrates easily with existing stylesheets.
# Heading → <h1>, **bold** → <strong>, `code` → <code> Frequently Asked Questions
Does this tool work offline?
Yes. Once the page has loaded (and marked.js has been fetched from the CDN once), conversion runs entirely in your browser with no internet connection required.
Which Markdown features are supported?
The converter supports headings, bold, italic, strikethrough, inline code, fenced code blocks, ordered and unordered lists, links, images, blockquotes, horizontal rules, and GitHub-style tables.
Is my text sent to a server?
No. All processing happens locally in your browser using marked.js. Your Markdown never leaves your device.
Can I convert HTML back to Markdown?
This tool converts Markdown to HTML only. For the reverse, try a dedicated HTML-to-Markdown tool or a library like Turndown.
Why does my table not render correctly?
Markdown tables require a header row and a separator row of dashes (---). Make sure each column is separated by a pipe (|) and the separator row has at least three dashes per column.
What is the formula for Markdown to HTML conversion?
Each Markdown token maps to an HTML tag: # Heading → <h1>, ## → <h2>, **bold** → <strong>, *italic* → <em>, `code` → <code>, ```block``` → <pre><code>, [text](url) → <a href>, and > quote → <blockquote>.
