This is a public test instance with rate limits \u2014 **do not use in production**.\n\nFor production, you have two options:\n\n**Option 1 \u2014 Docker (if you self-host n8n):**\nYou need Gotenberg running alongside n8n. The simplest way is adding it as a service in your `docker-compose.yml` \u2014 the same file where your n8n service is defined:\n```yaml\nservices:\n # ... your n8n service ...\n gotenberg:\n image: gotenberg/gotenberg:8\n restart: always\n```\n\nAfter saving, run `docker compose up -d` to restart your stack. Gotenberg will be accessible at `http://gotenberg:3000` from inside your n8n container \u2014 just update the URL in this node.\n\n**Option 2 \u2014 Google Cloud Run (if you use n8n Cloud or don't have access to Docker):**\nDeploy the `gotenberg/gotenberg:8` image to Google Cloud Run and use the generated URL as your Gotenberg endpoint.\n\n**Customization:**\nYou can configure PDF output settings through the Body Parameters of this node, including:\n- Page margins (top, bottom, left, right)\n- Default headers and footers\n- PDF metadata (author, title, subject, etc.)\n\nFor the full list of available options, check the [Gotenberg documentation](https://gotenberg.dev/docs/routes#convert-with-chromium)."
