Gotenberg

Gotenberg is a developer-friendly, containerized HTTP API for converting many document formats into PDF and performing related PDF operations. It wraps proven conversion engines so you can run consistent document generation in any environment without installing complex dependencies.

Key Features

• HTML and URL to PDF rendering via Chromium
• Office document conversion (e.g., Word, Excel) to PDF via LibreOffice
• Modular architecture with configurable modules and routes
• Container-first distribution for reproducible deployments
• PDF workflows such as conversion and merging
• Asynchronous processing via webhooks, with configurable headers and HTTP methods

Use Cases

• Generate invoices, reports, and other PDFs from HTML templates in backend services
• Convert user-uploaded Office documents to PDFs in a microservice pipeline
• Automated document generation/processing with webhook-based delivery to storage or downstream systems

Limitations and Considerations

• Conversion fidelity depends on underlying engines (Chromium/LibreOffice) and document complexity
• Rendering and conversion can be resource-intensive; capacity planning is important for high throughput

Gotenberg fits well as a stateless document conversion microservice in container-based stacks. Its API-driven approach and modular design make it practical for both simple PDF generation and more automated, asynchronous document workflows.
