PDF to LaTeX

Convert PDF documents to LaTeX format using MinerU. Best suited for academic papers and documents with formulas or complex layouts.

Install

npm install -g mineru-open-api
# or via Go (macOS/Linux):
go install github.com/opendatalab/MinerU-Ecosystem/cli/mineru-open-api@latest

Quick Start

# Convert PDF to LaTeX (requires token)
mineru-open-api extract paper.pdf -f latex -o ./out/

# With VLM model for better accuracy on complex layouts
mineru-open-api extract paper.pdf -f latex --model vlm -o ./out/

# From arXiv URL
mineru-open-api extract https://arxiv.org/pdf/2309.10918 -f latex -o ./out/

Authentication

Token required:

mineru-open-api auth             # Interactive token setup
export MINERU_TOKEN="your-token" # Or via environment variable

Create token at: https://mineru.net/apiManage/token

Capabilities

• Supported input: .pdf (local file or URL)
• Output format: LaTeX (-f latex)
• LaTeX output requires extract with token — not available in flash-extract
• Use --model vlm for papers with complex math, tables, or multi-column layouts
• Language hint with --language (default: ch, use en for English)

Notes

• LaTeX output (-f latex) is only available via extract with token
• --model vlm gives higher accuracy but may have rare hallucination risk; use pipeline for guaranteed fidelity
• Output goes to stdout by default; use -o to save to a file
• All progress/status messages go to stderr; document content goes to stdout
• MinerU is open-source by OpenDataLab (Shanghai AI Lab): https://github.com/opendatalab/MinerU
