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:
docker-compose up --build -d
Accessing the Web Page
Once the container starts, open your web browser and navigate to: http://localhost:5000
Stopping the Service
docker-compose down
2. Using Docker CLI Directly
If you prefer using standard Docker commands instead of Docker Compose:
Build the Docker Image
docker build -t doc-to-pdf-converter .
Run the Web Server
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
docker run --rm -v "<local_dir_path>:/data" doc-to-pdf-converter python /app/converter.py /data/<input_filename> /data
Examples
- PowerShell (Windows):
docker run --rm -v "${PWD}:/data" doc-to-pdf-converter python /app/converter.py /data/report.docx /data - CMD (Windows):
docker run --rm -v "%cd%:/data" doc-to-pdf-converter python /app/converter.py /data/report.docx /data - Bash (Linux / macOS):
docker run --rm -v "$(pwd):/data" doc-to-pdf-converter python /app/converter.py /data/report.docx /data
