Nano Banana 2 Image to Image: AI Photo Editor
Image to image is the best BananaGen workflow when you already have a reference photo, product shot, portrait, sketch, or composition. Upload the image, describe what should change, and tell the model what must stay unchanged.

Nano Banana 2 as a Photo Editor
"Image to image" and "AI photo editor" describe the same thing here. You are not painting over pixels with brushes — you upload a photo and say what should change in plain language, and the model returns a new version.
What that replaces:
- Background removal and replacement without cutting a mask by hand.
- Object removal by naming what should go.
- Restyling a portrait or product shot without a reshoot.
- Format changes — the same subject recomposed for a vertical or square crop.
What it does not replace: pixel-exact retouching, text you need set precisely, and anything where the original must be preserved byte-for-byte. The model regenerates the image rather than editing it in place, so treat the output as a new version, not a corrected file.
Keep a Face or Label Exactly as It Is
The most common edit is putting a real person or a real product into a different scene without the identity drifting. Say the lock explicitly — the model will drift otherwise:
Use the uploaded photo as the exact identity and subject reference. Preserve the face, hairstyle, clothing, pose, body proportions, and expression exactly. Replace the background with [new scene] and match the lighting direction to it. Maintain realistic perspective, shadows, and depth, and blend the edges seamlessly. Do not alter the subject.
For a product, swap the identity clause for preserve the product shape, label text, and camera angle exactly.
How to Edit an Image

Copy This Edit Prompt
Keep the main product, label, shape, and lighting direction unchanged. Replace the background with a warm minimalist studio set, add realistic shadows, preserve clean edges, no extra text, no watermark.
Prompting Tips for Better Edits
- Say what must stay unchanged before describing the new style.
- Avoid changing too many things in one prompt.
- Use clear words like “preserve”, “replace”, “remove”, “soften”, and “center”.
- For products, mention label, edges, shadows, and material.
- For portraits, mention identity, expression, pose, and lighting.
