1. Tutorial Introduction

MarkItDown is a lightweight, plug-and-play Python document conversion tool launched by the Microsoft team in August 2025. It aims to efficiently and structurally convert various common document and rich media formats into Markdown, providing an optimized input format specifically for text understanding and analysis pipelines of large language models (LLMs).

This tool systematically solves the core problems of structural information loss and semantic element omission when converting complex document formats (such as PDF and PPT) into plain text. Its design does not pursue visual fidelity for human reading, but prioritizes ensuring that key document logical structures (such as titles, lists, tables, links, etc.) are preserved for downstream AI processing, achieving a balance between format compatibility, structural fidelity, and processing efficiency.

This tutorial uses a single RTX 5090 graphics card as the default resource.
