VS Code extension

Markdown Viewer & Reader adds a fast, clean Markdown preview to VS Code with rich rendering (tables, diagrams, math) and export tools.

Install

What it does

  • Live preview panel that stays in sync as you type
  • GitHub Flavored Markdown (GFM) rendering (tables, task lists, code fences)
  • Diagrams: Mermaid, Graphviz/DOT, Markmap
  • Math rendering
  • Export to HTML or PDF

Quickstart

  1. Open any .md file.
  2. Run Markdown Viewer & Reader: Open Markdown Preview (Command Palette), or use the preview icon in the editor title bar.
  3. To export, run:
    • Markdown Viewer & Reader: Export to HTML

Tip: PDF export opens a temporary HTML file in your browser and uses the print dialog (“Save as PDF”).
