Marp CLI

What is Marp CLI?

Marp CLI is the command-line interface for the Marp (Markdown Presentation Ecosystem) project. You write your slide deck in plain Markdown with Marpit's directives, and Marp CLI converts it to HTML, PDF, PPTX, PNG, or JPEG — perfect for sharing on the web, printing, or importing into PowerPoint.

Key features

• Plain Markdown authoring with a simple --- separator between slides
• Local front-matter and global directives to control theming, pagination, sizing, and more
• Built-in and custom CSS themes — including the official default and gaia themes
• Math typesetting via KaTeX, plus Mermaid diagrams, emoji shortcodes, and syntax highlighting via Prism
• Multiple output formats — HTML (with web UI), PDF, PPTX, PNG, JPEG
• Watch mode for live preview while authoring
• Plugin system to extend directives, themes, and output formats
• Bundled VS Code extension for in-editor preview and export

Why Marp?

Marp is one of the original and most widely used Markdown slide tools, with a stable CLI, a thoughtful ecosystem of themes, and bindings for React and Vue if you want to embed slides in a web app. If you want to write your talk in Markdown and ship it anywhere — Markdown source in Git, HTML on the web, PDF for handouts, PPTX for stakeholders — Marp CLI is the most batteries-included option.
