Gotenberg review
A focused, self-hosted PDF conversion API with broad document and PDF operations.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Gotenberg is a self-hosted, Docker-based HTTP API for developers integrating PDF workflows into applications and services. It accepts URLs, HTML, Markdown, Microsoft Office files, OpenDocument files, and plain text, using Chromium and LibreOffice for conversion. The platform is suited to teams that want to deploy document conversion within their own infrastructure rather than adopt a hosted PDF editor or a form-focused document system.
Its strongest advantage is breadth within conversion and PDF manipulation. Gotenberg can convert web pages and files to PDF, then merge, split, rotate, flatten, encrypt, watermark, and stamp the results. It also reads and writes metadata and bookmarks, supports attachments, and can convert documents to PDF/A and PDF/UA. Factur-X and ZUGFeRD support adds a defined path for e-invoicing documents. PDF processing can run asynchronously through webhooks, while remote URLs can provide input files. These capabilities make it suitable for backend workflows that need more than basic file conversion.
The deployment model shapes the buying decision. Gotenberg is distributed as open-source Docker images and exposes an API for self-hosted use, with integrations for S3, MinIO, and Google Cloud Storage. That fits engineering teams managing their own services, storage, and operational environment. It is less suitable for buyers seeking a visual authoring application, built-in dataset-driven document generation, or fillable forms. Choose Gotenberg when API-based conversion and PDF operations are the priority; consider another product when business users need document templates, data merging, or form workflows.
