Image OCR

Extract text and content from images using MinerU. Supports photos, screenshots, scanned documents, and any image containing text.

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

# Quick OCR from image (no token required)
mineru-open-api flash-extract photo.png

# Save to directory
mineru-open-api flash-extract screenshot.jpg -o ./out/

# From URL
mineru-open-api flash-extract https://example.com/image.png

# Specify language (default: ch)
mineru-open-api flash-extract photo.png --language en

# Precision OCR with token (better accuracy, no size limit)
mineru-open-api extract photo.png --ocr -o ./out/

# With VLM model for complex layouts or mixed content
mineru-open-api extract photo.png --ocr --model vlm -o ./out/

Authentication

No token needed for flash-extract. Token required for extract:

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: .png, .jpg, .jpeg, .jp2, .webp, .gif, .bmp (local file or URL)
  • flash-extract: quick OCR, no token, max 10 MB / 20 pages, Markdown output
  • extract: token required, higher accuracy with --ocr, supports --model vlm for complex images
  • Language hint with --language (default: ch, use en for English documents)
  • Formula recognition available via extract --formula

Notes

  • For scanned documents or low-quality images, use extract --ocr --model vlm for best results
