MinerU overview and key facts (October 2026)

MinerU is an open-source toolkit that converts PDFs, scanned images and Office documents into Markdown, JSON and other formats that language models can use. It suits teams building RAG or agent systems on large, mixed document collections.

MinerU is developed by OpenDataLab, which operates under the Shanghai AI Laboratory. Version 4.0 bundles parsing, a local document library and service tools. It accepts PDF, images, DOC/DOCX, PPT/PPTX, XLS/XLSX, RTF, OpenDocument, EPUB, OFD, HTML and CSV, and renders to Markdown, HTML, LaTeX, DOCX, EPUB, PDF and structured JSON. It offers a Python SDK, an API, batch conversion, a router for several services and a web interface. As of September 28, 2026 the repository had about 80,800 GitHub stars. An online service with API is available at mineru.net.

• Parses difficult layoutsThe Standard and Advanced tiers use models for layout analysis and a visual language model for demanding pages. Multi-column reports, tables and formulas come out as structured text that a RAG system can index.
• Reads scans and photosThe Basic tier and above apply OCR and model-based parsing to scanned or photographed documents. Paper-based records become searchable without manual typing.
• Feeds agents with citable sourcesThe document library caches results, lets agents search content and continue page by page, and keeps stable citation locators. Answers can point back to the exact block in the source.

• Documents are not uploaded to the official service automatically; remote parsing is an explicit choice.
• Supports OFD and other formats common in Chinese public administration alongside Western Office formats.
• Model backends are configurable, including llama.cpp, vLLM and LMDeploy for the visual language model.

Developed by OpenDataLab at Shanghai AI Laboratory; it also supports OFD, the Chinese standard format for electronic documents.

Read the MinerU Open Source License: it is based on Apache 2.0 but adds conditions, so have legal review it before commercial use. If you use the hosted service at mineru.net, clarify where documents are processed and on what terms, since we found no prices or data terms on its homepage in September 2026. Self-hosting needs Python 3.10 to 3.14 and GPU capacity for the higher tiers.
