How to Use Nano Banana 3
Generate photorealistic images from text in three simple steps — no design skills or sign-up required. Edit existing photos with natural language.
Step 1: Describe Your Image
Enter a text prompt describing the image you want to create. Be specific about subject, composition, lighting, and style. You can also upload a reference image for image-to-image editing.
Nano Banana 3 accepts natural language — write as if you're describing the image to a skilled artist. The more detail you provide, the better the result. Instead of "a dog in a park," try "a golden retriever running through autumn leaves in Central Park, warm afternoon light, shallow depth of field, shot on 85mm lens."
Step 2: Choose Your Settings
Configure your output: Resolution (1K / 2K / 4K), Aspect Ratio (1:1, 16:9, 9:16, 4:3, 3:4), and Style Preferences (photorealistic, illustration, concept art, minimalist).
For character consistency across multiple images, enable the consistency toggle and upload reference photos. Nano Banana 3 supports up to 14 reference images for complex compositions.
Step 3: Generate and Download
Click Generate and wait for your result (typically 10–30 seconds depending on resolution). Preview the output, then download in PNG format with full commercial usage rights.
Want to refine? Describe changes in natural language — Nano Banana 3 supports multi-turn conversational editing, so you can iterate without starting over. All generated images include SynthID watermarking for AI provenance transparency.
Edit Existing Images
Upload any image and describe what you want to change in plain English. Nano Banana 3 handles object removal, background swaps, lighting changes, and multi-image blending.
Upload Your Image
Switch to the "Image to Image" tab and upload your reference image. Supported formats are JPEG, PNG, and WEBP.
Upload up to 14 reference images to combine elements, maintain character identity, or match styles across generations.
Describe Your Edit
Write a prompt describing what you want to change. Be specific about what to keep and what to modify.
Examples: "Remove the person in the background", "Replace the background with a sunset beach", "Make the lighting warm and golden", or "Apply a cinematic color grade".
Generate & Compare
Click Generate and review the result alongside your original. The editing workflow is conversational: make one change, see the result, then ask for the next adjustment.
No need to start from scratch each time. Image editing uses the same credit system as text-to-image — quality and aspect ratio settings apply equally.
When to use Image-to-Image: This mode works best when you have a visual starting point — a rough sketch, an existing photo to restyle, a product shot that needs a new background, or a reference image whose composition you want to preserve while changing the style.
Nano Banana 3 Prompt Tips
The difference between a mediocre result and a stunning one is often just a better prompt. Replace vague adjectives with specific cinematographic or design language.
Be Specific with Subjects
"a dog"
"A golden retriever puppy sitting on a white studio backdrop, soft rim lighting, 85mm lens, shallow depth of field"
Give Clear Edit Instructions
"make it better"
"Increase contrast, add warm golden-hour lighting from the left, sharpen the subject's eyes"
Specify Text Precisely
"add text"
"Add the text 'SUMMER SALE' in bold white sans-serif font centered at the top, with a subtle drop shadow"
Use Design Language for Style
"change the style"
"Apply a Wes Anderson color palette with pastel pinks and yellows, symmetrical framing, centered composition"
Describe Composition Clearly
"a poster for my business"
"A minimalist coffee shop poster, 'Brew & Co' in serif font, steaming latte illustration, earth-tone background, 2:3 aspect ratio"
Control Lighting & Mood
"good lighting"
"Soft golden-hour side lighting with warm tones, shot on 35mm lens, f/2.8 aperture, cinematic mood"
Prompt structure formula: [Subject] + [Setting] + [Lighting] + [Camera/Lens] + [Style/Mood]. Following this order consistently produces high-quality, predictable results.

Pro Tips for Better Results
- Keep text under 15 words. Nano Banana 3 handles text rendering with high accuracy, but shorter text produces cleaner results.
- Use cinematographic language. Instead of "nice lighting," specify "soft golden-hour side lighting, 35mm lens, f/2.8 aperture."
- Upload high-quality references. Use at least 1024px wide images for professional output. For character consistency, upload at least 3 reference photos.
- Iterate, don't overload. Generate a base image first, then use conversational editing to refine individual elements step by step.
