Nano Banana 3
Nano Banana 3 is a browser-based image generator and editor built around text prompts, uploaded references, and natural-language edit instructions. You can start from scratch, refine an existing photo, or blend ideas from multiple images while picking resolution up to 4K, aspect ratio, and PNG or JPG output from one studio-style workspace.
Where many generators treat references as a single style transfer, Nano Banana 3 pushes harder on multi-image guidance (up to 10 references on its Nano Banana 2.1 model), in-image typography for posters and packaging, and a Layers workflow alongside standard text-to-image and image-to-image modes. It also ships zero-credit utilities such as a 2x AI image enhancer and a background remover, which is unusual for a credit-metered product site.
The site speaks directly to ecommerce sellers, marketers, fashion and interior designers, educators, and game concept artists, with showcase galleries spanning product ads, cinematic stills, and architecture studies. Creator testimonials on the homepage focus on pre-shoot mood boards, campaign comps, and client-facing visual drafts rather than one-click social memes.
Usage is credit-based: generation cost depends on model, resolution, and batch size, with one-time credit packs that never expire and optional monthly subscriptions whose allowances refresh each billing cycle. NSFW generation is explicitly blocked, and exports ship without a watermark.
