Gotenberg

Project13.2K

Self-host a Docker API for document-to-PDF conversion and practical PDF operations.

What you can build

  • Convert invoice HTML or a URL into a PDF using the documented Chromium conversion workflow.
  • Build an endpoint that sends Office documents to Gotenberg and returns PDFs through its LibreOffice conversion workflow.
  • Use the documented merge operation to assemble uploaded PDFs into a single packet.
  • Build a URL or HTML screenshot workflow using Gotenberg’s documented screenshot capability.
  • Create a document-processing step that adds a watermark or updates metadata on PDFs.

Try this prompt

Build a small service that accepts an HTML invoice and optional uploaded PDFs, converts the invoice to PDF through a configured Gotenberg endpoint, and returns the resulting document. Keep the original inputs unchanged, report conversion errors clearly, and make the endpoint configurable. Use only documented API routes and add a simple end-to-end test for the request and returned PDF.

Get started

  1. Run the service

    Follow the official getting-started documentation to run the Gotenberg Docker image and make its HTTP API available to your application.

  2. Send a conversion request

    Submit files as multipart/form-data to the documented Chromium or LibreOffice route that matches your input, then handle the returned PDF.

  3. Add PDF operations

    Consult the official documentation for merge, watermark, metadata, or other supported PDF routes before building those steps into your workflow.

License & notes

MITMIT-licensed software; retain the license notice when distributing it. Self-hosting requires compute and hosting resources for the Docker service. The supplied sources do not specify infrastructure costs or any paid API or model requirements.

  • This is a self-hosted Docker API, so you must operate its service and provide hosting resources; the supplied sources do not state resource requirements or costs.
  • The documented conversion paths rely on Chromium and LibreOffice; confirm the relevant route and supported input format in the official documentation.
  • MIT distribution requires retaining the copyright and permission notice. No paid API or model costs are specified in the supplied evidence.
