Another way to open Nano Banana Pro
- Write a Clear, Design-Oriented Prompt
Clearly define your desired composition, including title placement, visual hierarchy, and style.
Example:
“Cartoon-style banana celebration scene in a futuristic control room. A glowing golden banana floats above a sci-fi platform. Cute anthropomorphic bananas around it using laptops, tablets, and taking selfies. Monitors display banana characters. Add confetti, bright lighting, and a banner saying “Nano Banana Pro is free for all, Come to GlobalGPT”. Vibrant colors, smooth shading, playful mood, 4K.”
- Add text + optional brand assets
Nano Banana Pro can cleanly render English, Chinese, and multilingual text directly on the image. You may also upload your logo, color references, or previous covers for consistency.
- Generate & Refine
Use short editing prompts to fine-tune layout, contrast, fonts, or color tone. Adjust prompt and regenerate if needed.
- Export for Your Blog Platform
For best results:
- Blog header: 1600 px wide
- Social share image: 1200×628 px
- Retina/HiDPI: export a 2× version
