Convert Marp Markdown files to polished PPTX presentations

Marp2PPTX: Enhanced Marp to PowerPoint Conversion

What is Marp2PPTX?

Marp2PPTX is a Python package designed to convert Marp Markdown files into polished, editable PowerPoint presentations. While Marp's own PowerPoint export tool is functional, it has several limitations and issues, such as improper font handling, unnecessary background objects, and fragmented text boxes. Marp2PPTX addresses these issues, ensuring that the exported presentations are clean, professional, and ready for further editing.

Why Use Marp2PPTX?

Marp2PPTX improves upon Marp's default PowerPoint export by:

• Fixing font rendering issues (e.g., ensuring proper handling of Segoe UI font).
• Removing unnecessary background objects that bloat the file size.
• Combining fragmented text boxes into cohesive units.
• Respecting slide margins to prevent text overflow.
• Accurately replicating Marp's advanced background image syntax.

This tool is ideal for users who rely on Marp for Markdown-based slide creation but need high-quality, editable PowerPoint files for professional use.

How to Use Marp2PPTX

Prerequisites

Before using Marp2PPTX, ensure you have the following installed:

1. Python 3.10 or higher or uv: Required to run the Marp2PPTX package.
2. Marp CLI: The Marp command-line tool is used to generate intermediate HTML files from Markdown. Install it via npm:

   npm install -g @marp-team/marp-cli
   

3. LibreOffice: Mandatory for the Marp CLI to create editable PowerPoint files. Ensure LibreOffice is installed and accessible from the command line.

Marp2PPTX is available as marp2pptx on PyPI.

Invoke Marp2PPTX directly with uvx:

uvx marp2pptx --help
uvx marp2pptx .\example.marp.md --open-pptx

Or install Marp2PPTX with uv (recommended), pip, or pipx:
