What is Google Nano Banana?

Nano Banana is Google's family of image-generation and editing models in Gemini. Google's current instructions describe Nano Banana 2, 2 Lite and Pro. You can upload an image and describe the change you want, then inspect the result before using it.

Where can a business use image editing?

  • Product mockups: explore logo placement before production.
  • Marketing drafts: compare backgrounds or color choices.
  • Team imagery: try an edit with the person's permission.

Treat generated images as drafts. Check that the final image accurately represents what you intend to show.

How to Access Nano Banana

Getting Started with Gemini

  1. Open Gemini and sign in with an eligible account.
  2. Upload an image you are allowed to use and enter the edit you want.
  3. For an existing generated image, Google's current desktop instructions use Library, the selected image and Chat. Follow the current help instructions if your interface differs.
  4. Review the result before downloading or publishing it.

The original interface screenshots below are illustrations; they are not a current navigation checklist.

Pricing and Account Access

Check Google's current image-generation help for model access and account requirements. Available models and quotas depend on your account. For an automated integration, use the Gemini API pricing documentation for the model you intend to use; API charges are separate from the app's subscription options.

Before Uploading Business Images

Use images you own or have permission to upload and edit. Get permission before using another person's likeness. Review Google's account and privacy guidance and your organization's rules before uploading confidential material. Work or school account terms can differ from personal-account terms.

Keep an original copy. Inspect spelling, logos, faces and product details before publishing. Label a mockup when it could be mistaken for a real product or location.

Best Practice

Review each output against the original and your brief. Use a qualified designer or photographer when an image needs exact branding, accurate product details or a faithful representation of a person.

Review Before Publishing

Use the examples to plan an edit, keep the original file and check the output. Get the needed permissions and confirm that the image says what you intend. Current account access and model choices are documented in Google's image-editing help.
