Pros & Cons 优缺点

Use Cases 应用场景

MarkItDown is widely used across the AI development ecosystem. Here are the most common scenarios:

📄 Universal File-to-Markdown Conversion

Convert PDF, DOCX, PPTX, XLSX, images (OCR), HTML, CSV, JSON, XML, ZIP, and audio files to clean Markdown with a single function call.

🤖 LLM Document Preprocessing

Prepare diverse document formats for LLM ingestion—convert everything to Markdown first so your RAG pipeline only needs to handle one format downstream.

🔧 Batch Document Pipeline

Walk a directory tree of mixed-format files, convert everything to Markdown, and output a structured folder ready for chunking and embedding.

Known Limitations & Gotchas 已知局限与注意事项

• Complex multi-column PDF layouts often lose their column structure in the conversion
• Embedded images in Word/PowerPoint are dropped (not converted) unless you use the image description feature with an LLM
• Very large documents (100+ pages) can be slow — no streaming or chunked processing
• Scanned PDFs (image-based) require OCR preprocessing and are not handled natively
