Fenced

A browser-based converter that turns Markdown into self-contained HTML with decorated code blocks, and can also convert HTML back to clean Markdown. It solves the problem of code screenshots going stale and being unreadable. It targets developers, marketers, and designers who need to share code in blogs, docs, or emails. It runs entirely client-side with no uploads, and offers multiple themes and export options.
