deepseek-ocr-cli 0.4.1

CLI tool for OCR using DeepSeek-OCR model via Ollama

DeepSeek OCR CLI

Command-line tool for OCR using DeepSeek-OCR via Ollama. Runs locally with no API keys or cloud dependencies.

Features

• Local processing with no API keys or usage costs
• Powered by Ollama for efficient local inference
• Supports PDFs and images (JPG, PNG, WEBP, GIF, BMP, TIFF)
• Batch processing for multiple files and directories
• Parallel page processing for faster PDF OCR
• Clean markdown output with HTML tables converted to markdown
• Progress tracking for multi-page PDFs
• Terminal interface with progress bars and summary tables

Requirements

• Python 3.10+
• Ollama installed and running
• deepseek-ocr model pulled in Ollama

Installation

1. Install Ollama

# macOS/Linux
brew install ollama

# Or download from https://ollama.ai

2. Pull the DeepSeek-OCR model

ollama pull deepseek-ocr

3. Install the CLI

pip install deepseek-ocr-cli

Alternative: Install from source

git clone https://github.com/r-uben/deepseek-ocr-cli.git
cd deepseek-ocr-cli
pip install -e .

Quick Start

# Process a single image
deepseek-ocr document.jpg

# Process a PDF
deepseek-ocr paper.pdf

# Process all files in a directory
deepseek-ocr ./documents/ --recursive

# Custom output directory
deepseek-ocr doc.pdf -o ./results/

# Custom prompt
deepseek-ocr form.jpg --prompt "Extract table data in markdown format"

# Extract page images from PDF
deepseek-ocr paper.pdf --extract-images

# Parallel processing for faster PDF OCR (2-4 workers recommended)
deepseek-ocr large-document.pdf -w 2

# Extract and analyze embedded figures with AI descriptions
deepseek-ocr paper.pdf --analyze-figures

Commands

process (default)

Process documents and images with OCR.

deepseek-ocr process document.pdf
# or simply
deepseek-ocr document.pdf

Output Format

The CLI generates markdown files with clean, structured output:

---
source: /path/to/document.pdf
processed: 2025-12-01T15:30:00
pages: 3
processing_time: 18.45s
model: deepseek-ocr
backend: ollama
---

## Page 1

[Extracted content from page 1...]

## Page 2

[Extracted content from page 2...]

Output Processing

Automatically applied to all OCR results:

• HTML tables converted to markdown tables
• Bounding box annotations removed
• HTML entities decoded
• LaTeX math expressions preserved

Performance

Typical performance on Apple Silicon M3 Max with 200 DPI, JPEG encoding:

• Simple receipt/form: ~10 seconds
• Standard text pages: ~15-20 seconds per page
• Dense tables/charts: ~30-40 seconds per page
• Very complex pages: Up to 2 minutes (rare)

Example: 1-page receipt processed in 11 seconds (tested).

Processing time varies based on content density. The tool uses 200 DPI and JPEG encoding for optimal speed while maintaining quality. Timeout is set to 30 minutes per page for extremely dense documents.

Configuration

Create a .env file to customize settings:

DEEPSEEK_OCR_MODEL_NAME=deepseek-ocr
DEEPSEEK_OCR_OUTPUT_DIR=output
DEEPSEEK_OCR_EXTRACT_IMAGES=false
DEEPSEEK_OCR_INCLUDE_METADATA=true
DEEPSEEK_OCR_LOG_LEVEL=INFO
OLLAMA_URL=http://localhost:11434

Programmatic Usage

from pathlib import Path
from deepseek_ocr import ModelManager, OCRProcessor

model_manager = ModelManager(model_name="deepseek-ocr")
model_manager.load_model()

processor = OCRProcessor(
    model_manager=model_manager,
    output_dir=Path("./results"),
    workers=2,  # Parallel page processing (default: 1)
)

result = processor.process_file(Path("document.pdf"))
print(result.output_text)

processor.save_result(result)

model_manager.unload_model()

Troubleshooting

Ollama not running

# Start Ollama
ollama serve

Model not found

# Pull the model
ollama pull deepseek-ocr
