MarkItDown

MarkItDown converts various formats (PDF, HTML, PowerPoint, Word) into Markdown, enhancing text readability and context retention. Since LLMs derive context from formatting cues like headings and sections, Markdown helps preserve structure for better comprehension. In RAG-based applications, our teams used MarkItDown to pre-process documents into Markdown, ensuring logical markers (headers, subsections) remained intact. Before embedding generation, structure-aware chunking helped maintain full section context which improves the clarity of query responses, especially for complex documents. Widely used for documentation, Markdown also makes MarkItDown’s CLI a valuable developer productivity tool.
