MinerU

MinerU turns complex documents into structured Markdown or JSON for LLM, RAG, and agent workflows. It handles PDF, DOCX, PPTX, XLSX, images, and web pages, with support for scanned documents, handwriting, multi-column layouts, and cross-page table merging.

It uses a VLM plus OCR dual engine with 109-language OCR recognition. Output follows human reading order, removes headers and footers automatically, and converts formulas to LaTeX and tables to HTML. It also supports native DOCX, PPTX, and XLSX parsing, plus MCP Server and native LangChain, Dify, and FastGPT integration.

MinerU ships a web version, a desktop client, and an API. It supports private, fully offline deployment and runs on a range of GPUs and AI accelerators. The project is released under the MinerU Open Source License, based on Apache 2.0.
