Upload, describe, transform
Start from a photo instead of a blank canvas. Upload one or more images, describe the result, and Nano Banana redraws it while keeping faces, products and layout recognizable.
Image to image AI turns an existing picture into a new one from your instructions. On NanoBanana you upload up to 8 reference images, describe the change (a new style, background, outfit or season) and Nano Banana 2 (20 credits) or Nano Banana Pro (45 credits) returns the result in 1K, 2K or 4K. New accounts get 40 free credits.
Watercolor, anime, oil painting, 3D render or film looks, with the original composition intact.
Swap backgrounds, seasons, weather or lighting and leave the subject untouched.
Put a product, person or pet from one image into another, or mix up to 8 references.
Change one object, color or detail and keep the rest of the picture as it was.
Add one to eight photos; the first one is usually the base.
Say what to change and what to keep, in plain words.
Nano Banana 2 for speed at 20 credits, Pro for detail at 45.
Save the result in 1K, 2K or 4K, or keep editing it.
Text to image starts from nothing, so the model invents every detail. Image to image starts from your picture, so faces, products, poses and layout carry over and you only describe the difference. That makes it the right tool whenever the result has to look like something real: your product, your room, your pet or yourself.
When you need a brand-new scene, start with text to image and switch to image to image to refine the result.
The model changes what you mention and keeps what you protect explicitly, so name both:
AI that takes an existing image as input and creates a new one from your instructions, keeping the parts you want and changing the rest, such as the style, background or clothing.
New accounts get 40 free credits, enough for 2 Nano Banana 2 images. After that each image costs 20 credits with Nano Banana 2 or 45 with Pro.
Up to eight PNG, JPEG or WebP images of up to 10 MB each. Refer to them as image 1, image 2 and so on in your prompt.
Nano Banana keeps faces, products and layouts close to the originals when you ask it to, but it redraws the image, so small details can change. Keep your original files.
Upload a photo and describe the change. The first images are on us.
