MinerU

What is MinerU?

MinerU is a document parsing and OCR tool that helps users extract readable content from PDFs, images, and common office documents. It is designed for workflows that need text, structure, and layout-aware output from source documents rather than simple file viewing. Common uses include converting files to Markdown, extracting text from scanned pages, processing multi-page documents, and working with structured outputs for analysis or automation. MinerU supports formats such as PDF, images, DOCX, PPTX, XLSX, and other document types, and it offers command-line, API, and WebUI-based workflows. On macOS, users are most likely to use it as part of a local document-processing workflow for research, knowledge capture, OCR, or downstream AI and automation tasks.

Key features

• Extract text and structure from PDFs and scanned images
• Convert supported documents into Markdown and other structured outputs
• Process Office files such as DOCX, PPTX, and XLSX
• Run document parsing locally through command-line workflows
• Use a WebUI for interactive document processing tasks
• Handle long documents with page-by-page or block-based reading workflows

Safety overview

Status: Mostly safe

MinerU is intended for local document parsing and OCR, so access to the files you choose to process is central to how it works. That kind of file access is normal for this type of tool, but you should use it thoughtfully with sensitive documents because extracted content may be saved in new output files or intermediate results. Keep it if you actively use document conversion, OCR, or structured extraction on your Mac, and use trusted document sources when possible.

Recommendation: Keep MinerU if you use it for document extraction, OCR, or conversion workflows. If you do not use those features, removing it is usually reasonable, but any related parsing tools, saved outputs, or custom workflows that depend on it may stop working until it is reinstalled.
