Image-to-Recipe PDF n8n Workflow: OpenRouter, Apify & Drive

Turn a dish photo into a print-ready recipe PDF—then store it in Google Drive

This Image-to-Recipe PDF n8n workflow takes an image URL from an n8n Form submission, uses OpenRouter (Google Gemini) to generate a recipe, converts it to a one-page A4 PDF via Apify, and automatically uploads the result to Google Drive.

What this workflow does

• Receives an n8n form submission containing a required dish image URL.
• Analyzes the photo and generates recipe text by sending the image URL to OpenRouter using a Google Gemini image model.
• Creates printable output by using an additional OpenRouter (Google Gemini) chat model step to transform the recipe text into:
  • a one-page, self-contained HTML document
  • a target PDF filename
• Converts HTML to PDF by running the Apify actor igview-owner/html-to-pdf-api.
• Retrieves the generated PDF from Apify’s key-value store using the last run’s output filename.
• Uploads the PDF to a specified folder in Google Drive via an OAuth2 credential.

Use cases

• Recipe generation for SaaS apps: users submit a dish image link and instantly receive a downloadable PDF.
• Restaurant or creator workflows: generate consistent, printable recipe pages for menus, blogs, or guides.
• Automation engineers: a practical example of connecting OpenRouter, Apify, and Google Drive in n8n.

Technical details

• Nodes/stack: Form Trigger, HTTP Request, Google Drive, Apify (apify-n8n-nodes-apify), and an n8n LangChain Agent setup (n8n-nodes-langchainagent).
• LLM provider: OpenRouter (with Google Gemini models) using your API key (no hard-coded tokens).
• PDF conversion: Apify actor igview-owner/html-to-pdf-api.
• Storage: uploads the resulting PDF to your configured Google Drive destination folder.

After you test the trigger, share the generated form/webhook URL with users who will submit image links.
