What it is

MarkItDown is a lightweight Python utility from Microsoft that converts almost any document format — PDFs, Word, PowerPoint, Excel, images, HTML, audio — into clean Markdown output. It preserves structural information (headings, lists, tables, links) while discarding visual formatting, producing output that modern LLMs understand natively. With 122k+ GitHub stars, it has become a standard pre-processing step in AI document pipelines. The project exists because Markdown sits at the sweet spot between plain text and rich markup that LLMs handle well. It’s intentionally a pre-processing utility, not a standalone document converter — the output is optimized for feeding into an LLM context or RAG pipeline rather than for human reading.
Use this when you need to feed arbitrary documents into an LLM pipeline without losing structural context — turn a 50-page PDF into a form Claude or GPT can actually reason over.
