Extract text, tables, images, and metadata from 75+ file formats including PDF, Office documents, and images. Native Python bindings with async/await support, multiple OCR backends (Tesseract, EasyOCR, PaddleOCR), and extensible plugin system.


## Installation

### Package Installation




Install via pip:

```bash
pip install kreuzberg
```

For optional EasyOCR support:

```bash
pip install kreuzberg[easyocr]
```




### System Requirements

- **Python 3.10+** required
- Optional: [ONNX Runtime](https://github.com/microsoft/onnxruntime/releases) version 1.24+ for embeddings support
- Optional: [Tesseract OCR](https://github.com/tesseract-ocr/tesseract) for OCR functionality



## Quick Start

### Basic Extraction

Extract text, metadata, and structure from any supported document format:

```python
import asyncio
from kreuzberg import extract_file, ExtractionConfig

async def main() -> None:
    config = ExtractionConfig(
        use_cache=True,
        enable_quality_processing=True
    )
    result = await extract_file("document.pdf", config=config)
    print(result.content)

asyncio.run(main())
```


### Common Use Cases

#### Extract with Custom Configuration

Most use cases benefit from configuration to control extraction behavior:


**With OCR (for scanned documents):**

```python
import asyncio
from kreuzberg import extract_file

async def main() -> None:
    result = await extract_file("document.pdf")
    print(result.content)

asyncio.run(main())
```




#### Table Extraction


```python
import asyncio
from kreuzberg import extract_file

async def main() -> None:
    result = await extract_file("document.pdf")

    content: str = result.content
    tables: int = len(result.tables)
    format_type: str | None = result.metadata.format_type

    print(f"Content length: {len(content)} characters")
    print(f"Tables found: {tables}")
    print(f"Format: {format_type}")

asyncio.run(main())
```




#### Processing Multiple Files


```python
import asyncio
from kreuzberg import extract_file, ExtractionConfig, OcrConfig, TesseractConfig

async def main() -> None:
    config = ExtractionConfig(
        force_ocr=True,
        ocr=OcrConfig(
            backend="tesseract",
            language="eng",
            tesseract_config=TesseractConfig(psm=3)
        )
    )
    result = await extract_file("scanned.pdf", config=config)
    print(result.content)
    print(f"Detected Languages: {result.detected_languages}")

asyncio.run(main())
```





#### Async Processing

For non-blocking document processing:

```python
import asyncio
from pathlib import Path
from kreuzberg import extract_file

async def main() -> None:
    file_path: Path = Path("document.pdf")

    result = await extract_file(file_path)

    print(f"Content: {result.content}")
    print(f"MIME Type: {result.metadata.format_type}")
    print(f"Tables: {len(result.tables)}")

asyncio.run(main())
```
