# QuickPDF Studio: OCR Microservice

A dedicated, self-hosted OCR extraction API built with **FastAPI**, **EasyOCR**, and **PyMuPDF**.

## Features
- **Pure REST API**: No frontend bloat, just high-performance endpoints.
- **Multi-Format Support**: JPG, PNG, WebP, and multi-page scanned PDFs.
- **Localized**: Pre-configured for English ('en') and German ('de').
- **Privacy First**: Files are processed in memory and never persisted to disk.
- **Docker Ready**: Easy deployment on any system.

## Quick Start (Local)

1. **Install Dependencies**:
   ```bash
   pip install -r requirements.txt
   ```

2. **Run Server**:
   ```bash
   uvicorn main:app --reload
   ```

3. **Check Health**:
   ```bash
   curl http://localhost:8000/health
   ```

## API Usage

### `POST /ocr`

  -F 'file=@sample.pdf'
```

- **Resources**: This service is optimized for CPU. It is recommended to have at least 2GB of RAM available.
