Workflows with Nano Banana

1. Resizing for Compliance

Use the "Nano Banana Change Image Size" capability or the resolution parameter to reach target dimensions.

• For Amazon/Shopify/eBay: Set resolution to 2K (approx. 2048px) to ensure high-quality zoom.
• For Etsy: Use 1024 or 2K depending on the original quality.

2. Adjusting Aspect Ratio

Use the aspect_ratio parameter to ensure consistency across your store.

• Square (1:1): Best for Amazon and Shopify product grids. Use aspect_ratio: "1:1".
• Portrait (4:5 or 2:3): Good for lifestyle shots and Etsy. Use aspect_ratio: "4:5".
• Landscape (3:2 or 16:9): Best for hero banners. Use aspect_ratio: "3:2".

3. Background and Style

Use the prompt parameter to achieve the desired look.

• Amazon Main Image: prompt: "Product on a pure white background, high-quality photography, 8k resolution, professional studio lighting."
• Lifestyle Shot: prompt: "Product in a modern home setting, soft natural lighting, high-quality lifestyle photography."

4. Format Optimization

Use the output_format parameter based on your needs.

• JPEG (output_format: "jpg"): Recommended for Amazon and most general ecommerce uses to keep file sizes manageable.
• PNG (output_format: "png"): Best for Shopify when you need high quality or transparency.
• WebP: If you are integrating with a custom frontend, use WebP for maximum speed.
