MinerU review
A developer-focused toolkit for extracting complex PDF content into structured formats.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MinerU is an open-source document parsing and PDF conversion toolkit from OpenDataLab. It is designed for developers, researchers, and agent-based document workflows that need to turn PDFs, scanned documents, images, Office files, and other supported inputs into structured content. The toolkit covers local command-line workflows, Python integration, a Gradio-based WebUI, batch conversion, and a self-hosted V1 HTTP API across web, Windows, macOS, Linux, API, and self-hosted environments.
Its strongest area is complex-layout extraction. MinerU includes OCR for scanned PDFs and images, along with processing for tables, formulas, figures, and document layouts. Conversion targets include Markdown, HTML, LaTeX, DOCX, EPUB, PDF, structured content, and Content List V1/V2. Batch conversion supports directories and multiple inputs, making the toolkit a practical fit for document pipelines rather than one-off file conversion. The Python SDK and HTTP API also provide integration paths for programmatic workflows.
MinerU’s main trade-off is its technical orientation. Local workflows, SDK integration, WebUI use, and self-hosted API deployment give teams control over how document processing runs, but they also place the product closer to an engineering toolkit than a consumer-first hosted converter. Choose MinerU when open-source access, complex PDF parsing, OCR, structured exports, and automation matter most. Choose a simpler converter instead when the priority is a straightforward end-user interface with minimal deployment or development involvement.
MinerU pros and cons

- Where it doesn't
- Primarily suited to developer, research, and agent-based workflows
- Local and self-hosted deployment requires technical setup
- Less oriented toward consumer-first, hosted conversion workflows
