Now, let’s dive into five practical, creative, and time-saving image editing techniques you can do with Google Nano Banana in 2025.

1. Removing Objects from an Image

Traditionally, removing unwanted objects—whether it’s a photo bomber, coffee cup, or graffiti—took skillful cloning and retouching. With Google Nano Banana, it’s as simple as writing:

Prompt: “remove coffee cups from the table”

For straightforward images, the edit works on the first attempt, delivering a clean, realistic replacement background. But what about trickier scenarios, like graffiti hidden in a corner? That’s where contextual prompts shine. By highlighting the area and pairing it with instructions, you guide Nano Banana to focus precisely on that region.

This contextual intelligence makes Nano Banana ideal for:

• Cleaning product photos for e-commerce.
  
• Removing distractions in travel or real estate photography.
  
• Preparing professional headshots without messy backgrounds.
  

What used to be 20 minutes of editing is now a 20-second interaction.

2. Colorizing Old Photos

Photo colorization has long fascinated both historians and artists. Until recently, it required meticulous work, manual brush strokes, and lots of guesswork. Nano Banana transforms this painstaking process into a near-instant edit.

Prompt: “Colorize this image”

With just one command, black-and-white photographs come to life with natural skin tones, environmental hues, and subtle shading. For example, a 1950s portrait can be revitalized in vibrant colors, ready for framing or archival display.

Of course, the AI isn’t flawless—complex backgrounds may retain some monochrome elements, like cars or signs. But for most family photos, vintage portraits, and historic records, Nano Banana delivers compelling results in seconds.

This opens doors for:

• Genealogy projects: Breathing new life into family albums.
  
• Museums and archives: Quickly preparing colored visuals for exhibitions.
  
• Social media nostalgia posts: Turning old snapshots into engaging content.
  

The emotional value of seeing a loved one’s black-and-white photo reimagined in full color is simply priceless.

3. Adding or Modifying Text on Billboards

Marketers, rejoice. Nano Banana is redefining how quickly ad mockups can be created. Imagine you’re testing a new slogan or campaign. Instead of commissioning a full shoot, you can take any billboard photo and update it instantly.

• Scenario 1: Adding text
  Prompt: “add text to the billboard: ‘Let’s create something great with Super AI’”
  The plain billboard is instantly branded with your message.
  
• Scenario 2: Replacing text
  Prompt: “Change the text on the billboard that says ‘Don’t stop ’til you get enough’ to ‘Remember you’re doing your best.’”
  

Here’s where Nano Banana impresses most: it mimics the original font family and style. The new text blends seamlessly into the design, as though it were part of the photo all along.

The only hiccup? Sometimes text alignment isn’t perfect, requiring a quick follow-up. Still, compared to manual Photoshop edits, this is a huge timesaver.

Practical applications include:

• Rapid prototyping for ad agencies.
  
• A/B testing slogans on realistic visuals.
  
• Personalized branding mockups for clients.
  

In a world where content moves fast, Nano Banana helps marketing teams keep up.

4. Maintaining Character Consistency

If you’ve ever tried using AI tools to generate characters, you know the struggle: keeping a mascot, person, or brand character consistent across multiple scenes. Nano Banana changes that.

Say you have a panda mascot. Upload the image and simply instruct:

Prompt: “make the character in this image drive a bus.”

Nano Banana not only places your mascot in the new setting, but ensures the panda’s defining traits remain intact. In another edit, you could request:

Prompt: “make the character in this image dance in a club, with a realistic setting.”

The result? The same recognizable mascot, now featured in multiple creative contexts.

This is revolutionary for:

• Branding campaigns: Mascots or characters appearing consistently across ads, packaging, and merch.
  
• Storytelling: Authors or illustrators maintaining visual continuity for characters in books or comics.
  
• Entertainment: Animators quickly testing how characters look in different environments.
  

Consistency builds recognition—and Nano Banana ensures your audience never loses track of your core characters.

5. Creating Branding Assets

One of the most practical uses for Nano Banana is branding visualization. Instead of imagining how your logo might look on a mug, card, or app screen, you can see it instantly.

Examples include:

• Prompt: “mug with this logo on it” → Your logo wrapped around a coffee mug.
  
• Prompt: “mobile phone with a screen that shows this logo and text ‘Build the future’” → A realistic digital mockup of your app screen.
  
• Prompt: “mobile phone with a screen that shows this logo in the hands of a virtual influencer” → A polished promo shot, ready for campaigns.
  

Nano Banana handles perspective, lighting, and texture blending seamlessly, so your designs look natural in context.

This drastically reduces the time and cost of creating brand mockups, empowering startups, agencies, and solo creators alike. Whether you’re pitching to clients, posting on social media, or designing your first product launch, Nano Banana makes professional-quality previews effortless.
