Markdown Preview — Write Markdown and See It Rendered Live
Markdown is a lightweight markup language that lets you format text using simple, readable symbols — a hash for a heading, asterisks for bold, a dash for a list item — instead of clunky HTML tags. It has become the default writing format for README files, GitHub issues, documentation, static-site blog posts, chat apps, and note-taking tools. This live preview shows your Markdown rendered as formatted HTML in real time, side by side with the source, so you can see exactly how it will look as you type.
The editor supports the common GitHub-Flavored Markdown features you will use every day: headings, bold and italic emphasis, ordered and unordered lists, links, inline code and fenced code blocks, blockquotes, horizontal rules, and tables. Type on the left, and the formatted result appears immediately on the right — no build step, no save button, no round trip to a server.
Everything runs locally in your browser, so your writing stays private. For safety, any raw HTML you paste into the input is shown as literal text rather than being executed, so a preview can never run unexpected markup. Common uses include drafting a README before committing it, checking how a blog post or comment will render, learning Markdown syntax by experimenting, formatting notes, and quickly converting a rough outline into clean structured text you can copy elsewhere.
How to use the Markdown Preview
- Type or paste Markdown into the editor on the left.
- Watch the formatted preview update live on the right.
- Use standard Markdown: # for headings, ** for bold, - for lists, ` for code, > for quotes.
- Clear the sample text to start from scratch.
