MinerU is a document parsing tool that converts PDFs, images, DOCX, PPTX, and XLSX files into machine-readable Markdown and JSON. It handles layout analysis, OCR in 109 languages, formula-to-LaTeX conversion, and table extraction, making documents ready for LLM and RAG pipelines.

Use cases

• convert pdfs to markdown for llm training
• extract text and tables from scanned pdfs
• prepare documents for rag pipelines
• parse research papers with formulas into latex
• convert docx and pptx files to
• ocr documents in multiple languages
• extract structured data from complex pdf layouts

When to choose

• you need LLM-ready markdown or JSON from complex documents
• documents contain formulas, tables, or multi-column layouts
• you need OCR for scanned or garbled PDFs
• you want a CLI, API, or WebUI for batch document conversion

When to avoid

• you only need simple text extraction from plain digital PDFs
• you need pixel-perfect visual fidelity of the original document
• you cannot run GPU-accelerated models locally and need lightweight processing
