# Docker-based Document to PDF Converter & Web Service

A robust, Docker-based Python service that converts `.doc`, `.docx`, `.ppt`, `.pptx`, `.xls`, and `.xlsx` files to PDF. It supports both a **modern, drag-and-drop web UI** (with batch ZIP downloads) and a **command-line script** for local automation.

It uses **LibreOffice headless mode** for high-fidelity conversion, preserving original fonts, layouts, images, and alignments.


---

## Features
- **Sleek Web UI**: A beautiful, premium dark-themed web page featuring glassmorphism design and responsive drag-and-drop file inputs.
- **Multiple File Upload**: Upload and convert multiple files in a single batch.
- **On-the-Fly ZIP Download**: Compiles all converted PDFs into a single, non-nested ZIP file download.
- **Zero-Footprint Storage**: Converts files in a containerized temporary directory, which is automatically and immediately deleted once the conversion and download are completed.
- **Microsoft Core Fonts**: Pre-accepts and installs Microsoft Core Fonts (`msttcorefonts`) alongside other metric-compatible fallback fonts to maintain accurate layout proportions.
- **Dual Support**: Operates as a Flask web service or as a one-off CLI tool.
- **Docker Compose Integration**: Easily orchestrate the service with single command setup.

---

## 1. Using Docker Compose (Recommended)

To build and run the web application in background (headless) mode:

```bash
docker-compose up --build -d
```

### Accessing the Web Page
Once the container starts, open your web browser and navigate to:
**[http://localhost:5000](http://localhost:5000)**

### Stopping the Service
```bash
docker-compose down
```

---

## 2. Using Docker CLI Directly

If you prefer using standard Docker commands instead of Docker Compose:

### Build the Docker Image
```bash
docker build -t doc-to-pdf-converter .
```

### Run the Web Server
```bash
docker run --rm -p 5000:7860 doc-to-pdf-converter
```

---

## 3. Using the CLI Script (Alternative)

If you wish to use the one-off CLI converter script instead of the web server, override the default command and mount the target document folder:

### Syntax
```bash
docker run --rm -v "<local_dir_path>:/data" doc-to-pdf-converter python /app/converter.py /data/<input_filename> /data
```

### Examples
- **PowerShell (Windows)**:
  ```powershell
  docker run --rm -v "${PWD}:/data" doc-to-pdf-converter python /app/converter.py /data/report.docx /data
  ```
- **CMD (Windows)**:
  ```cmd
  docker run --rm -v "%cd%:/data" doc-to-pdf-converter python /app/converter.py /data/report.docx /data
  ```
- **Bash (Linux / macOS)**:
  ```bash
  docker run --rm -v "$(pwd):/data" doc-to-pdf-converter python /app/converter.py /data/report.docx /data
  ```
