MinerU: PDF Document Parsing Tool

Hello everyone, I'm Achao! Today I'm introducing an AI tool that really caught my eye—MinerU. This isn't just any ordinary PDF parser; it's a true intelligent assistant that genuinely understands document content.

Project Overview

MinerU is an open-source document parsing tool developed by the OpenDataLab team, specifically designed to convert complex documents like PDFs into machine-readable formats such as Markdown and JSON. Simply put, it acts as a ”document translator” that understands the structure and content of documents, then outputs formatted results.

Most impressive of all, MinerU emerged during the pre-training process of the Shusheng-Puyu large language model, giving it a natural advantage in handling scientific literature. Just imagine—those complex formulas, tables, and multi-column layouts? MinerU handles them all with ease!

Key Feature Highlights

🎯 Intelligent Content Extraction

• Precise Structural RecognitionAutomatically identifies headings, paragraphs, and lists while preserving the original document's hierarchical structure.
• Smart Element FilteringAutomatically remove distracting elements such as headers, footers, footnotes, page numbers, etc.
• Reading Order OptimizationWhether single-column, multi-column, or complex layouts, it outputs text that aligns with human reading habits.

📊 Multimodal Content Processing

• Image and DescriptionExtract images and associate them with corresponding descriptive text.
• Table ParsingConvert the table to HTML format while preserving its structure and data integrity.
• formula recognitionAutomatically recognize mathematical formulas and convert them to LaTeX format.
• Multi-language supportOCR supports detection and recognition in 109 languages.

⚡ High Performance and Compatibility

• Multiple backend optionsSupports both pipeline and VLEM parsing backends to meet varying precision and speed requirements.
• Cross-platform supportCompatible with Windows, Linux, and Mac platforms
• Hardware AccelerationSupports multiple hardware acceleration solutions including GPU (CUDA), NPU (CANN), and MPS.
• Pure CPU operationEven without a dedicated graphics card, it can still function normally.

Technical Breakthrough: MinerU2.5

The newly released MinerU 2.5 version is truly impressive! This compact model with just 1.2 billion parameters outperformed top multimodal large models like Gemini 2.5-Pro, GPT-4o, and Qwen2.5-VL-72B in the OmniDocBench evaluation!

Core Strengths:

• Ultimate Energy Efficiency Ratio1.2B parameters achieve performance surpassing models with over 10 billion parameters.
• Two-stage reasoningDecoupled layout analysis and content recognition, with higher accuracy
• Native high resolutionSupports high-resolution document parsing for richer detail
