Guide
A practical guide to Nano Banana and Nano Banana Pro: where to use them, how to prompt, and how to get consistent, high-resolution results.
To use Nano Banana, open an app that runs it, such as NanoBanana, write a prompt or upload a photo, describe the change in plain words and choose Nano Banana 2 for speed or Nano Banana Pro for detail. On NanoBanana an image costs 20 or 45 credits, new accounts get 40 free credits, and results download in 1K, 2K or 4K.
Describe a scene and get a finished image in seconds.
Upload a photo and say what to change; the rest stays as it was.
Reuse the same person or mascot across many images.
Posters, labels and signs with readable lettering, strongest in Nano Banana Pro.
Sign up on NanoBanana; new accounts get free credits.
Describe the subject, setting, style and light, or upload images to edit.
Nano Banana 2 costs 20 credits and is faster; Pro costs 45 and renders fine detail and text best.
Adjust the prompt, regenerate, and download in 1K, 2K or 4K.
Nano Banana understands full sentences better than keyword lists. A reliable structure is subject, action, setting, style and light, plus what must stay unchanged when you edit:
Use Nano Banana Pro when the image is final: product shots, posters with text, detailed illustrations and 4K prints. It follows long prompts more carefully and renders small text better, at a higher price per image. A good workflow is to explore with Nano Banana 2 and switch to Pro for the version you publish.
Edits work best when you change one thing at a time and say explicitly what to keep. For bigger changes, such as a new background and a new outfit, run two edits in a row. Refer to uploads as image 1, image 2 and so on when you combine several pictures.
Google offers limited free use in the Gemini app. On NanoBanana every new account gets 40 free credits, enough for 2 Nano Banana 2 images, with no subscription required.
No. NanoBanana runs Nano Banana in the browser on desktop and mobile, so there is nothing to download or configure.
Upload the photo, describe the change in one sentence and say what should stay the same, for example “replace the sky with a sunset, keep the people unchanged”.
You may use images you create on NanoBanana for personal and commercial projects, provided your prompts and uploads respect other people's rights and our terms.
