Frequently Asked Questions
Quick answers to common questions about Nano Banana
A credit is a unit of generation usage on Nano Banana. Each image generation—whether text-to-image or image-to-image—consumes exactly 1 credit. Credits are purchased in packs and deducted from your balance with each generation. This simple system keeps pricing transparent and fair.
You get 1 free generation without signing up — just open the generator and try it. Sign up (email only, no credit card) to receive 3 additional free credits. That's 4 total free generations to test the platform before purchasing.
No, unlimited free generation is not available. Every AI image generation costs computational resources. Unlimited free access would lead to abuse, slow performance, and degraded quality. Our credit system ensures sustainable, reliable service. See the unlimited clarification page for more details.
Output images are generated at high resolution suitable for most professional uses. The exact resolution varies by aspect ratio selection. All outputs are high-quality PNG format. For specific dimension requirements, you may need to resize outputs in a photo editor after generation.
Uploaded images for image-to-image editing have a maximum file size limit to ensure fast processing. Most standard photos from phones and cameras work without issue. Very large files may need to be compressed before upload. The interface will notify you if a file exceeds the limit.
Start with proven templates from the prompt library rather than experimenting from scratch. Read the prompt guide to understand effective prompt structure. Make small, iterative changes when refining results. Avoid vague prompts that produce unpredictable outputs. Plan your prompt before clicking generate.
There are no strict rate limits for normal usage. However, extremely rapid consecutive requests may be temporarily throttled to prevent abuse and ensure fair access for all users. Normal human usage patterns are never affected by rate limiting.
Currently, each generation produces one image. Batch generation of multiple images in a single request is not supported. For multiple variations, you'll need to run separate generations, each consuming 1 credit. This gives you control over each output.
Nano Banana supports common aspect ratios: 1:1 (square), 16:9 (landscape), 4:3 (standard), 3:4 (portrait), and 9:16 (vertical/mobile). Choose the aspect ratio that best fits your intended use case. The AI optimizes composition for the selected ratio.
Yes, content policies prohibit generating harmful, illegal, or explicit content. The AI includes safety filters. Attempts to generate prohibited content will fail and may result in account action. Standard professional and creative use cases are fully supported.
Credits do not expire as long as your account remains active. You can purchase credits and use them at your own pace. However, extended account inactivity may eventually trigger cleanup policies. We recommend using credits within a reasonable timeframe.
API access is not offered at this time. All generation goes through the web interface. This allows us to maintain quality control, prevent abuse, and provide a consistent user experience. Programmatic access may be considered for future development.
