What is Nano Banana?
Nano Banana is an advanced AI image editor from Google. Rather than dragging sliders or using complicated tools, you tell it what you want in plain language and it does the heavy lifting. Want to change your outfit, add a new background or blend two photos together? Nano Banana understands complex instructions like “put me on a beach at sunset” or “turn my living room walls green”. It keeps faces and identities consistent across edits, blends new elements seamlessly into the original scene and even works with multiple images at once. Users love it because it produces photorealistic results in a single shot, making it perfect for content creators and marketers.
Getting Started
1. Access Nano Banana
Nano Banana lives on the web, so there’s no software to install. Head to nanobanana.ai or log into Google’s Gemini app (Gemini 2.5 Flash Image). You’ll see a “Start Editing” or “Launch Now” button on the homepage. Clicking it takes you to the editor interface.
Sign‑up/login: To save your work and use advanced features you’ll need an account. Choose Sign Up if you’re new, or Sign In if you already have one. You can usually sign in with your Google account. Some workplace accounts require the administrator to enable Gemini 2.5 Flash Image first. If you run into issues here, check that your Google Workspace has image editing enabled or try a personal account.
Step‑by‑Step Tutorial
Once you’re logged in, follow these steps:
1. Navigate the Dashboard
You’ll land on the Nano Banana dashboard. The interface is clean and simple. On the left you’ll see options like Image Editor, Batch Editor and Background Remover. In the centre is your workspace with an “Add Image” button and a text box labelled Main Prompt. To the right is an output gallery where your creations will appear.
2. Upload Your Image
Click Add Image and choose a photo from your device. You can drag and drop or browse. Nano Banana supports files up to about 50 MB. For the best results, choose a high‑resolution image with clear lighting. If you’re experimenting with character edits, start with a person or pet facing the camera.
Nano Banana also supports multiple images. If you want to blend yourself with your pet or put two characters in the same scene, upload both pictures now.
3. Write Your Prompt and Edit
In the Main Prompt box, describe exactly what you want. Natural language works great. For example:
“Change my shirt to a red hoodie and put me in front of a snowy mountain.”
“Blend this picture of me with my dog so we’re standing on a basketball court.”
“Replace the living‑room wall with dark green wallpaper and add a bookshelf.”
Nano Banana understands complex instructions and maintains character details. You can also perform multi‑turn editing: run the first edit, look at the result, and then add another prompt to refine it (e.g., “Add a coffee table” after placing furniture). Gemini’s updated model is designed to preserve your look while modifying specific parts of the image.
Once your prompt is ready, click Generate Now or Edit. The AI will process your request and display the result in seconds. You’ll see the edited image appear in the output gallery. If something looks off, refine your prompt and run it again. Because the model uses one‑shot editing, you often get great results on the first attempt.
4. Adjust Settings and Explore Tools
Nano Banana offers a toolbox of options:
Style/Format: If you want a certain mood, mention it in your prompt (e.g., “in watercolor style” or “cinematic lighting”). The AI can apply styles from one image to another—Google calls this “design mixing”.
Scene Preservation: The model blends new elements seamlessly into the background. If you need to keep the background intact, emphasise that in your prompt.
Batch Processing: Use the Batch Editor for multiple images at once—a time‑saver for product shoots or content batches.
Multi‑Image Context: Upload several images to maintain consistency across a series.
If you’re exploring through Flux AI (LMArena), you can choose from various editing tools such as inpainting, background removal or depth adjustments. According to the Flux tutorial, editing on their platform takes three simple steps: upload your image, choose your tools, then save and download.
5. Save and Export Your Results
When you’re happy with your edit, click Download or Save. Choose the format you prefer—JPEG or PNG. If you’re using the Gemini app, you can even turn your edited photo into a short video to share on social media. Remember that Google applies visible and invisible watermarks to indicate that images were AI‑generated.
You can also re‑upload the edited image for further modifications. For example, after changing the background of a room, upload the new image and ask for additional decor. This multi‑turn workflow helps you build complex scenes without starting from scratch.
Pro Tips for Best Results
Be specific with your prompts. The model understands complex instructions, but the clearer you are, the better the output. Describe colors, textures and positions (e.g., “dark green velvet chair on the left side”).
Use reference images. Upload a second image to guide the style. Nano Banana can apply the color and texture of one photo to objects in another.
Iterate with multi‑turn editing. Make one change at a time, then refine. You can paint walls in one edit and add furniture in the next.
Keep file sizes reasonable. Large images may slow processing. Stick to under 50 MB per image for smooth performance.
Take advantage of batch mode for consistent edits across multiple product shots or social media campaigns.
Common Issues & Fixes
| Issue | Quick Fix |
|---|---|
| Login problems | If you can’t log in with your work account, check with your admin to enable Gemini 2.5 Flash Image. Try using a personal Google account if necessary. |
| Slow results | Large files or high demand can slow the service. Compress your image or try during off‑peak hours. |
| Watermarks | All AI‑generated images include visible and invisible watermarks. This is intentional and cannot be removed. Plan your design with this in mind. |
| Editing the same image multiple times | You can re‑upload your edited image for multi‑turn editing. Use the output as a new input and continue refining. |
| Blurry or distorted outputs | Make sure your original photo is sharp and well lit. Use specific language in your prompt, and try refining the prompt if the result isn’t clear. |
Visual suggestion: Insert a small screenshot of a common error message with a simple caption (e.g., “login required”).
Real‑Life Use Cases
Students & hobbyists: Create artwork for school projects, fan art or personal portfolios without learning complex software. Imagine turning yourself into a comic‑book hero or placing your history project characters in different eras.
Businesses & marketers: Generate consistent product shots or ad images. Nano Banana maintains character and product consistency across multiple edits, making it ideal for marketing campaigns.
Content creators & influencers: Produce eye‑catching thumbnails, posters and story illustrations quickly. Blend yourself with different scenes or change outfits for each episode of your vlog. Combining photos of you and your pet on a basketball court becomes effortless.
Social media managers: Use batch mode to edit a series of promotional photos with consistent style. Mix textures and colors from one image to another to create a unique brand aesthetic.

Start by signing up and exploring the dashboard, upload your images, describe your edits in natural language, adjust settings to fine‑tune the look and save or share your creations.
