What is Nano Banana AI?
Nano Banana AI is a web-based AI tool that combines image editing and generation. It accepts user-uploaded images (JPG, PNG, WEBP, up to 10 MB each, max 8 images) or text prompts, and outputs edited or newly created images. The service is powered by Google's Gemini 3 Pro Image model, one of the most powerful AI image models currently available.
