MarkItDown

Convert documents and web content into clean LLM-ready Markdown.

MarkItDown is a Microsoft utility that converts a wide range of files and web pages (HTML, PDF, Office docs, images, audio) into clean Markdown optimized for LLM consumption. It preserves structure like headings, tables, and lists so models can reason over content reliably. It is notable for normalizing messy scraped or downloaded content into a single text format for ingestion.
