## Nano Banana - text and reference image generator

The current form supports prompt-only generation or image-led editing with up to four references, ten ratios, Auto framing in image mode, and output count.

## Nano Banana text and reference examples

The gallery illustrates portrait, character, product, style, background, and sticker directions; it is not evidence of consistency or an output guarantee.

### Edited Portrait

### Character Across Scenes

### Product Swap

### Style Transfer

### Background Change

### Sticker & Emoji Art

## Why Nano Banana

The live form owns the current prompt, reference, ratio, and output-count controls. Review every returned image against the submitted inputs.

### Text-led and image-led modes

Text mode starts from a required prompt. Image mode requires reference media plus a prompt, so choose the mode from the inputs available for the task.

### Up to four reference images

Image mode accepts one to four files. References condition a run but do not lock identity, products, text, background, or composition.

### JPEG, PNG, or WebP up to 10 MB

Each reference must match one of the three declared formats and stay within the 10 MB file limit.

### Ten ratios plus Auto

Text mode offers ten aspect ratios from 21:9 through 9:16. Image mode adds Auto so framing can follow the supplied source.

### One to four outputs

The output-count control offers one, two, three, or four results. Review the updated credit estimate before increasing count.

### Explicit prompt and time metadata

The prompt limit is 3,000 characters and model metadata estimates about 120 seconds. Neither value guarantees prompt adherence or completion time.

## Who uses Nano Banana text and reference input, and for what?

Designers, marketers, ecommerce teams, illustrators, and creators can use these candidate workflows to test prompt-led or reference-led images; every result still needs review.

### Photo-change concepts

Use a clear source photo and one requested change, then compare the result for unintended changes to the subject, lighting, background, and crop.

### Recurring-character studies

Supply consistent references to test a subject in new scenes, but reject identity drift rather than claiming guaranteed character preservation.

### Product mockups

Use product references for studio or lifestyle concepts and verify labels, proportions, colors, and regulated details before downstream use.

### Style explorations

Compare a requested visual direction across outputs while preserving the original source and checking what changed.

### Sticker and icon drafts

Generate small-format visual concepts, then inspect edges, transparency needs, facial details, and text before export.

### Campaign concept sets

Hold references and prompt structure constant while testing ratios or output count; do not assume a batch is automatically brand-consistent.

## Nano Banana text and reference FAQ

Answers about input modes, reference limits, formats, ratios, output count, configured credits and time, rights, and review boundaries.

### What is Nano Banana?

Nano Banana is a selectable image workflow in this app with text-led and image-led modes. The live form defines its prompt, reference, ratio, and output-count controls.

### Which input modes are available?

Text mode uses a required prompt. Image mode requires one or more references plus a prompt and adds Auto to the ratio choices.

### How many reference images can I upload?

Image mode accepts one to four reference files. More references do not guarantee stronger identity or composition preservation.

### Which reference formats and sizes are accepted?

The schema accepts JPEG, PNG, and WebP files up to 10 MB each. Unsupported files must be converted before upload.

### Which aspect ratios can I choose?

The form offers 16:9, 5:4, 4:3, 3:2, 1:1, 2:3, 3:4, 4:5, 9:16, and 21:9; image mode also offers Auto.

### How many outputs can one run request?

The output-count field offers one through four. Check the displayed credit estimate before submitting more than one.

### What time and credit estimates are configured?

Model metadata starts at 2 credits and estimates about 120 seconds. Queue conditions, count, and task state can change the observed result.

### Can generated images be used commercially?

Paid plans include this app’s commercial license; free-tier output is personal-only. You remain responsible for reference rights, applicable terms, and final use.

### What should I review before using an image?

Review prompt adherence, identity, anatomy, text, product details, background, crop, and unintended source changes. References guide the result rather than locking it.

### How many credits does Nano Banana use?

Nano Banana draws between 16 and 26 credits per run, depending on the model and length chosen in the form.

### What limits should I check before using Nano Banana?

Generated output from Nano Banana can contain visual, audio, or factual errors. Review each result before publishing, and upload only material you are authorized to use. Where the form accepts a reference image, supported files are JPEG, PNG, WebP up to 10 MB each.

### What happens to the files I upload to Nano Banana?

An upload is stored against your own account, not pooled with other people's. Deleting the account removes it: the control is in Settings under Security, the request is confirmed by email, and the erasure removes the stored objects it owns. How long anything else is kept, and which processors handle it, is stated in the privacy policy.

### Can I use what Nano Banana makes commercially?

Every paid plan includes a commercial licence for what Nano Banana makes; the free tier is for personal use.
