# Nano Banana Pro Image Generator

Generate from text or guide an edit with up to four reference images, then choose aspect ratio, 1K–4K resolution and one to four outputs.

> Canonical: https://stable-diffusion-web.com/nano-banana-pro

Nano Banana Pro accepts a prompt or up to four reference images, exposes 1K, 2K and 4K output, and requires paid-model access in this app.

## Nano Banana Pro reference examples at 1K to 4K

Six example directions covering portraits, product scenes, concept art, poster layouts, character studies and still life. Treat every result as an example to review, not a guaranteed capability claim.

### Cinematic Portrait

### Studio Product Shot

### Concept Art Landscape

### Poster With Clean Text

### Character Design

### Photoreal Still Life

## What Controls Does Nano Banana Pro Expose?

The live form defines the supported workflow: prompt-only generation or reference-guided editing, explicit size and framing choices, and a selectable output count.

### 1K, 2K and 4K Output

Choose 1K, 2K or 4K. A larger setting changes output size and credit use; it does not guarantee correct lettering, anatomy or fine detail.

### Ten Framing Choices

Prompt-only generation offers ratios from 1:1 and portrait formats through 16:9 and 21:9. Reference mode also offers Auto when the source framing should guide the result.

### Up to Four Reference Images

Reference mode accepts one to four JPEG, PNG or WebP files, each up to 10 MB. State what must remain recognizable and what may change.

### One to Four Independently Billed Outputs

Choose one, two, three or four outputs. The workflow creates separately billed jobs, so confirm the displayed total before submitting a larger batch.

### A 3,000-Character Prompt Field

The form accepts a required prompt up to 3,000 characters. Use concrete subject, composition and edit constraints; more words do not guarantee better instruction following.

### Paid Access and Rights Boundary

This is a paid model. Every paid plan includes this app's commercial license for generated work, subject to app terms and third-party rights in prompts, references and outputs.

## How to Configure a Generation

Choose the input mode first, then configure framing, size and output count from the controls that belong to that mode.

### Choose text or reference mode

Use Text to Image for a prompt-only composition. Use reference mode for one to four JPEG, PNG or WebP files of at most 10 MB each.

### Set framing, resolution and count

Choose an available aspect ratio, 1K, 2K or 4K, and one to four outputs. Review the current credit estimate before submitting.

### Inspect every returned image

Check required text, subject identity, product detail and composition at full size. Refine the prompt or references when any required element drifts.

## Nano Banana Pro use cases and 4K limits

These are practical starting points for the visible controls. Results remain variable and require human review before publication or client delivery.

### Marketing and Social Visuals

Draft posters, ads and social layouts, then verify every word, logo, disclosure and brand detail before publishing.

### Product and E-commerce Concepts

Use product references for studio or lifestyle concepts. Compare packaging, shape and small details against the source in every output.

### Concept Art and Illustration

Explore characters, environments and key art with explicit composition constraints, while treating continuity across separate runs as unverified.

### Photo Restyling

Guide a restyle from one or more source images. Specify protected elements because unchanged regions and identity are not guaranteed.

### Recurring Subject Studies

Use the same references across a set and review drift in faces, products, colors and proportions before accepting the sequence.

### Print and Wide Layout Drafts

Use portrait, square, landscape or 21:9 framing for covers and banners, then validate typography and print suitability outside the generator.

## Generation Questions

Direct answers about inputs, resolution, access, timing, output count, rights and the limits of reference-guided generation.

### What is Nano Banana Pro?

Nano Banana Pro is a selectable image-generation model in this app with text and reference-image modes, 1K–4K output settings and one-to-four output batches.

### Which reference files can I upload?

The reference workflow accepts one to four JPEG, PNG or WebP images, each up to 10 MB. At least one valid image is required in reference mode.

### Is paid access required?

Paid-model access and enough credits are required. The generator shows the current debit estimate before submission.

### How long should a generation take?

The form lists an estimated time of about two minutes. Queue conditions, output size and request complexity can make an individual job faster or slower.

### Which resolutions and aspect ratios are available?

The form offers 1K, 2K and 4K plus ten prompt-mode aspect ratios from portrait through 21:9. Reference mode also includes Auto.

### How does the output-count control affect cost?

One to four outputs can be requested. Each output becomes an independently billed generation job, so the total increases with the selected count.

### Can generated images be used commercially?

Every paid plan includes this app's commercial license for generated work. App terms and third-party rights in the prompt, references and output still apply.

### Does the workflow require a local installation?

No local model or GPU setup is required. The form runs in a browser, but sign-in, paid-model access and sufficient credits are required to submit.

### Do references guarantee character or product consistency?

Reference images guide the request but do not guarantee identity, product accuracy, typography or continuity. Compare every output with the source before publishing a set.

### How many credits does Nano Banana Pro use?

Nano Banana Pro draws 26 credits per run.

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

Generated output from Nano Banana Pro 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 Pro?

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 Pro makes commercially?

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