Nano Banana AI Product Mockup n8n Workflow (Gemini 2.5)

Create AI product mockups in n8n by compositing your product onto any model or template image

Nano Banana AI Product Mockup n8n Workflow (Gemini 2.5) takes a product image, a template/model image, and your prompt, then uses Google Gemini 2.5 via OpenRouter to generate polished marketing visuals—ideal for e-commerce and dynamic ad assets without a photoshoot.

What this workflow does

• Runs when a user submits the required inputs through an n8n Form Trigger.
• Converts the submitted images into Base64 strings so they can be sent in an API request.
• Sends a multimodal payload to the OpenRouter API using Gemini’s image generation model, providing:
  • the product image
  • the template/model image
  • your text prompt
• Receives the generated image as a Base64 output string.
• Converts the output into a file (via a “Convert to file” step) and extracts the result for downstream use.

Use cases

• Virtual try-on style visuals for apparel—place a product onto different models/templates.
• E-commerce advertising—generate consistent product-in-scene images for campaigns.
• Rapid creative iterations—try new prompts and layouts without reshooting products.
• Custom marketing material—quickly create variations for landing pages and storefronts.
