Nano Banana Prompts: 50 Best Examples for Image Editing

Nano Banana prompts need action, context, and constraints

Good Nano Banana prompts are edit instructions, not keyword lists. Because Nano Banana works inside Gemini's image editing flow, the prompt can refer to the current image, a reference image, and previous turns. Google DeepMind's Gemini image page positions Nano Banana around image generation and editing, and Google's Gemini blog update notes stronger support for multi-part editing instructions. The best Nano Banana prompts make each edit measurable.

Use this structure for most Nano Banana prompts:

Action + visual context + preservation constraint + final use.

Example:

Replace the background with a warm cafe interior, match the light direction, keep the product label unchanged, and prepare the image for a square product ad.

Product prompts

These Nano Banana prompts are useful for product photos and e-commerce assets. Save the Nano Banana prompts that preserve labels, shadows, and product shape most reliably:

1. Replace the background with a clean white studio wall and keep the product shadow natural.
2. Put the product on a walnut tabletop with soft morning light from the left.
3. Remove the price tag and preserve the original package shape.
4. Add condensation droplets to the bottle without changing the label text.
5. Create a premium dark hero image with subtle blue rim lighting.
6. Change the scene to a minimalist kitchen and keep the camera angle unchanged.
7. Clean dust and scratches from the product surface only.
8. Make three color-grade variants: warm, cool, and neutral.

For implementation, the Nano Banana API page explains how these prompts move from manual testing into production routing.

Portrait and character prompts

Use these Nano Banana prompts when identity preservation matters. In portrait workflows, Nano Banana prompts should protect eyes, nose shape, pose, and hair before changing the scene:

1. Keep the face identical and replace the background with a blurred city street at sunset.
2. Add soft studio lighting from the left without changing facial features.
3. Change the jacket to navy while preserving pose, hair, and expression.
4. Remove stray hair across the forehead and do not smooth the skin.
5. Convert the portrait into a corporate headshot with a neutral gray background.
6. Apply a black-and-white editorial style while keeping the same person.
7. Add small round glasses that match the lighting and face angle.
8. Restore the original eyes and nose shape if the edit changed identity.

Identity checks are essential. Ars Technica's report on Nano Banana noted Google's focus on improved editing behavior, but production teams should still review faces and likeness before publication.

Background and scene prompts

Background replacement is one of the strongest Nano Banana prompt categories. These Nano Banana prompts work because they specify both the new environment and the light-matching rule:

1. Replace the background with a tropical beach at sunset and match warm light on the subject.
2. Change the room to a modern co-working space with large windows.
3. Put the subject on a dark stage with a single soft spotlight.
4. Replace the wall with a deep teal solid color and keep clean edges around the hair.
5. Add a cozy library background with shallow depth of field.
6. Replace the sky with storm clouds and adjust the overall color grade.
7. Put the product on moss with soft forest light.
8. Change only the background; do not alter the foreground subject.

Marketing and social prompts

These Nano Banana prompts help create reviewable campaign drafts. Marketing Nano Banana prompts should leave blank space for final copy instead of asking the model to create finished typography:

1. Turn this product photo into a square Instagram ad with clean space for text at the top.
2. Create a LinkedIn banner with the subject on the left and empty dark space on the right.
3. Add a festive border and warm bokeh lights without covering the product.
4. Build a before-and-after layout showing original and edited versions side by side.
5. Create a premium launch teaser with deep blue background and subtle glow.
6. Make the composition suitable for a website hero at 16:9.
7. Remove clutter and simplify the background for a clean ad creative.
8. Keep all text areas blank so final copy can be added later.

Do not rely on generated text for final ads. Short labels may work, but exact typography should usually be rendered outside the model.

Adapting prompts for Pro and Nano Banana 2

Nano Banana prompts should be shorter for fast draft models and more constrained for higher-fidelity models. Google's Nano Banana 2 announcement frames newer versions around stronger image creation and editing, but the same prompt structure still applies.

Use Nano Banana vs Pro when deciding whether a prompt should route to a draft model or a final-render model. Use Nano Banana upres when the prompt has already produced a good image but the final asset needs more resolution.

Bottom line

The best Nano Banana prompts are specific, local, and protective. Say what should change, describe the visual context, and name what must stay unchanged. Keep each turn focused, verify faces and text, and save approved intermediate states before applying another edit.
