A Docker-based API for PDF conversion
Categories:
Gotenberg is a Docker-based, developer-friendly API for converting documents like web pages, HTML, Markdown, Office files, and PDFs into PDFs, and performing advanced PDF operations.
🚀 Overview
Gotenberg provides a stateless HTTP API to convert various document formats into high-quality PDFs using a single Docker container, eliminating the need to manage dependencies like Chromium or LibreOffice.
It solves the problem of reliable, pixel-perfect PDF generation and manipulation in applications, supporting dynamic content, JavaScript execution, and cloud integrations. It's built for developers, teams, and open-source projects needing production-grade PDF services without complexity.
Created to bundle powerful tools into one easy-to-deploy service, it's trusted by thousands of companies for its simplicity and performance.
✨ Key Features
- Web to PDF (what it does and why it matters): Converts URLs, HTML templates, Markdown to PDFs via headless Chromium; matters for pixel-perfect rendering with JS support, wait strategies, custom headers/cookies.
- Office Suite: LibreOffice converts .docx, .pptx, etc. (100+ formats); essential for legacy docs with PDF/A compliance.
- PDF Operations: Merge, split, encrypt, watermark using QPDF/pdfcpu/ExifTool; enables full PDF workflows.
- Cloud Native: Zero-copy with S3/GCS presigned URLs.
🛠 Tech Stack
- Backend: Go
- Runtimes: Chromium (headless), LibreOffice, QPDF, pdfcpu, ExifTool
- Database: None (stateless)
- Auth: None (API via headers)
- Hosting: Docker, Railway, Elestio, etc.
