Markdown Preview
Markdown is a lightweight markup language that uses plain-text formatting syntax (like # for headings and ** for bold) to create structured documents. It is the standard format for README files, documentation, and content on platforms like GitHub, Stack Overflow, and many blogging systems.

Which Markdown flavor does this support?
The tool uses the marked library, which supports CommonMark and GitHub Flavored Markdown (GFM) including tables, strikethrough, and task lists.
Can I copy the rendered HTML?
The Copy HTML button copies the rendered HTML output, which you can paste into any system that accepts HTML.
Does it support syntax highlighting in code blocks?
The tool renders fenced code blocks with the appropriate HTML structure. Syntax highlighting requires an additional CSS library not included here.
Is my text sent to a server?
All rendering runs locally in your browser using the marked library. No text is transmitted anywhere.
Can I use this to preview README files?
Paste the contents of any Markdown file including GitHub README files and see a live rendered preview.
