Why Use Our Markdown Editor

Markdown Syntax Quick Reference

Markdown is a lightweight markup language created by John Gruber in 2004. It is designed to be readable as plain text while being easily convertible to HTML. Markdown has become the standard format for README files, documentation, blog posts, forum comments, and technical writing across platforms like GitHub, GitLab, Stack Overflow, and Reddit.

The most commonly used Markdown elements include: headings (# for h1, ## for h2, etc.), bold text (**bold**), italic text (*italic*), links ([text](url)), images (![alt](url)), unordered lists (- item), ordered lists (1. item), code blocks (triple backticks), blockquotes (> text), and horizontal rules (---). Tables are created using pipes and dashes to define columns and rows.

For developers, Markdown supports fenced code blocks with optional language identifiers for syntax highlighting. Inline code is wrapped in single backticks. This makes Markdown particularly useful for technical documentation where you need to include code examples alongside explanatory text. Most modern platforms that render Markdown also support syntax highlighting for common programming languages.

Frequently Asked Questions

What Markdown syntax is supported?

This editor supports the full CommonMark specification via the marked.js library. This includes headings (h1 through h6), bold, italic, strikethrough, links, images, fenced code blocks with language hints, blockquotes, ordered and unordered lists, tables, horizontal rules, and inline code. The preview renders all of these elements with styled formatting.

Is my content saved anywhere?

No. Everything runs entirely in your browser. Your Markdown content is never sent to any server, stored in any database, or logged in any way. When you close or refresh the page, all content is lost unless you use the download buttons to save your work locally first.

Can I use this for GitHub README files?

Yes. This editor supports the same Markdown syntax used in GitHub README files. Write your content here, preview it to make sure it looks correct, and then download the Markdown file or copy the raw text directly into your repository's README.md file. Note that some GitHub-specific extensions like task lists may render slightly differently.

What is the difference between Markdown and HTML?

Markdown is a simpler, more readable way to write formatted text that gets converted to HTML. While HTML uses tags like <strong> for bold text, Markdown uses **asterisks**. Markdown is designed to be human-readable even in its raw form, whereas HTML is more verbose and harder to read. This editor converts your Markdown to HTML for preview and export.

Can I export the HTML for use on my website?

Yes. Click Copy HTML to copy the rendered HTML to your clipboard, or click Download HTML to save a complete HTML file. The exported HTML can be pasted directly into your website, blog CMS, email template, or any platform that accepts HTML content. The HTML output includes proper semantic tags like h1, h2, p, ul, and table.
