Does this skill require external API keys?

Basic conversion is handled locally. However, advanced features like AI-enhanced image descriptions via OpenRouter or Azure Document Intelligence require their respective API credentials.

Which file formats can MarkItDown convert?

MarkItDown supports a wide range of formats including PDF, DOCX, PPTX, XLSX, images (with OCR), audio (with transcription), HTML, CSV, JSON, XML, ZIP, EPub, and YouTube URLs.

Can I use MarkItDown for batch processing?

Yes, the skill includes patterns for iterating through directories to convert multiple files at once, perfect for building large-scale knowledge bases from existing document archives.

Why is Markdown the preferred output format?

Markdown is highly token-efficient, preserves structural hierarchy (like headers and tables), and is natively understood by Large Language Models, making it ideal for AI-driven analysis and RAG.

How does it handle images and diagrams?

It uses OCR to extract text from images and can leverage AI models to generate detailed text descriptions. Additionally, it can create new scientific schematics and diagrams to represent complex concepts visually.
