Html to PDF

Production-grade HTML to PDF conversion service powered by headless Chromium via Playwright.

Built for reliability under load, this service has been designed, stress-tested, and hardened for real-world, concurrent server-side environments.

Features

• High-fidelity HTML → PDF rendering using Chromium
• Fully configurable output (page format, orientation, scale, background rendering)
• Supports both inline preview and attachment download responses
• Engineered for high concurrency and sustained throughput
• Stable browser/context lifecycle management for long-running workloads
• Deterministic rendering with consistent results across environments

How to Run

Docker (Recommended)

Build the image:

docker build -t htmltopdf .

Run the container:

docker run -p 8080:8080 htmltopdf

The service will be available at:

http://localhost:8080/swagger

Fully containerized. No additional setup required.

Local Runtime (.NET 8)

After building the application, install Playwright dependencies manually:

From the project root, navigate to:

/bin/Debug/net8.0

Then run:

powershell ./playwright.ps1 install

This installs the required Chromium binaries and drivers for local execution.
