About
MarkItDown is a versatile utility developed by Microsoft that transforms over 15 file formats—such as PDF, DOCX, PPTX, and even audio files—into structured Markdown. By providing clean, text-based output, it enables Claude and other language models to process complex documents, spreadsheets, and presentations with high fidelity while optimizing token usage. Its advanced capabilities include OCR for scanned documents, speech-to-text for audio files, and AI-driven image descriptions, making it an essential tool for scientific research, data analysis, and automated document ingestion workflows within the Claude Code environment.
