FAQ

Nano Banana 2 Frequently Asked Questions

What is Nano Banana 2 and how does it work?
Nano Banana 2 is an AI image generator that creates images from a text prompt or an uploaded reference photo. Describe what you want, set an aspect ratio and resolution, and it renders a high-resolution result in seconds that you can refine with plain-language edits.
Is Nano Banana 2 free to use?
Yes. You can generate images online for free directly in your browser. Start typing a prompt, generate a result, and download it, with no software to install and nothing to buy before you try the tool.
Do I need to sign up or log in to get started?
No sign-up is required to start. Open Nano Banana 2, enter a prompt, and create your first image online in seconds, so you can test the speed and quality yourself before deciding to do anything else.
What image formats and resolutions are supported?
You can upload JPG, PNG, or WEBP reference images, and the tool generates output up to native 4K across multiple aspect ratios. Pick a lower resolution for quick drafts, then re-generate at 4K when you need a print-ready or high-detail final image.
Can I use Nano Banana 2 images for commercial projects?
The generator is built for real deliverables like ads, posters, product shots, and storyboards. Images you generate are yours to use in marketing, client work, and commercial projects, so you can take a result straight from prompt to published campaign.
Nano Banana 2 vs Nano Banana Pro: what's the difference?
Nano Banana 2 is the fast image model built for quick, high-volume generation, while Nano Banana Pro is a separate, heavier model tuned for maximum precision. This generator runs the fast Nano Banana 2 model, so you get 4K results in seconds, ideal for iterating on prompts and drafts.
How does the reference image keep characters consistent?
When you upload a reference photo, the model uses it to lock the identity of your character or product, then places that subject into whatever scene your prompt describes. It is the easiest way to build storyboards and campaigns without your subject changing between images.
How do I write better Nano Banana 2 prompts?
Write naturally and be specific. Name the subject, action, scene, lighting, and style, for example a golden retriever running through a park at golden hour. The more detail you give Nano Banana 2, the closer the first result lands, and you can fine-tune the rest with edits.
