Gotenberg

Gotenberg is a powerful Docker-powered stateless API designed to handle PDF operations with ease. It provides developers with a simple HTTP interface to interact with industry-standard tools like Chromium and LibreOffice, enabling seamless conversion of various document formats including HTML, Markdown, Word documents, Excel spreadsheets, and more into high-quality PDF files. Built with containerization in mind, Gotenberg is completely stateless, making it ideal for cloud-native applications, microservices architectures, and scalable document processing pipelines.

Common Use Cases

Web application developers integrate Gotenberg to generate PDF invoices, receipts, and reports from HTML templates without complex server-side rendering libraries. SaaS platforms use Gotenberg to provide document export functionality, allowing users to download content as PDFs. Marketing teams leverage it to convert landing pages and email templates into PDF format for offline distribution. Document management systems utilize Gotenberg's LibreOffice integration to convert Microsoft Office documents to PDF for standardized archival. DevOps teams deploy Gotenberg as a shared microservice to centralize PDF generation across multiple applications, reducing code duplication and maintenance overhead.

Why deploy Gotenberg on Hostinger VPS

Deploying Gotenberg on Hostinger VPS gives you dedicated resources for processing document conversions without competing with shared hosting limitations. The VPS environment provides consistent performance for batch PDF generation tasks and ensures responsive API endpoints even under heavy load. With full control over the Gotenberg instance, you can customize conversion parameters, configure security policies, and implement authentication to protect your API from unauthorized access. Hostinger VPS's reliable infrastructure ensures your document processing service remains available 24/7, critical for applications that generate invoices, reports, or user-facing documents in real-time. The isolated environment allows you to integrate Gotenberg with your other VPS-hosted applications securely, creating a complete self-hosted document processing solution without external API dependencies or per-conversion fees.
