What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses plain text formatting syntax that is easy to read and write, and can be converted to structurally valid HTML. Markdown is used everywhere — from README files on GitHub, to blog posts, documentation sites, note-taking apps, and much more.

GitHub Flavored Markdown (GFM)

This previewer supports GitHub Flavored Markdown (GFM), which extends the original Markdown spec with features like tables, strikethrough text (~~like this~~), task lists (- [x] done), and fenced code blocks with language identifiers.

How to Use this Previewer

Simply type or paste your Markdown into the left editor panel. The right panel updates in real-time as you type. When you are happy with the result, use the Copy HTMLbutton to grab the rendered output, or Export .html to download a complete, self-contained HTML file with inline styles ready for embedding.

Is my content saved?

Your Markdown is processed 100% in your browser. We do not store or transmit your content. If you reload the page, the content will reset to the default example.
