If you want to know how to use Gemini for photo editing, the short version is: upload a photo to Gemini, describe the change in plain words, and Gemini's image model (Nano Banana 2) returns an edited version. You can change backgrounds, fix small details, try new styles, or combine several photos into one, all from a chat box, on the web or in the Gemini app.
It works on a free Google account, with some limits. Google's help center says you must be 18 or over to edit images in Gemini, and that free accounts download images at 1K resolution while a Google AI plan downloads at 2K. Below are the exact steps, prompts that get clean results, and the honest limits.
What Gemini photo editing can do
Google's help page lists what Nano Banana 2, the model Gemini uses for images, is built for:
- Local edits: quick, specific changes to one part of an image (remove a cup from a table, change a shirt color).
- Character consistency: keep the same person or character looking the same across several images.
- Combining images: upload multiple photos and ask Gemini to blend them into a new scene.
- Better text rendering: add text to images with more accurate spelling.
- Instruction following: handle longer, more detailed requests.
In plain terms, Gemini is good at "change this, keep the rest." It's not a layer-based editor like Photoshop. You describe; it redraws.
How to use Gemini for photo editing: step by step
On a computer
- Go to gemini.google.com and sign in.
- Upload the photo you want to edit (or open one Gemini made earlier: Open Sidebar → Library, click the image, then click Chat under it).
- In the text box at the bottom, type the edit you want.
- Click Submit.
- When you like the result, hover over it and click Download full size. You can also choose More → Export to Docs.
On Android or iPhone
- Open the Gemini app (or gemini.google.com in your browser).
- Upload a photo from your device, or tap Menu → Library and pick an image Gemini created.
- Tap Chat under the image, type your edit and tap Submit.
Tip: make one change per message. "Make the sky sunset orange" then "now remove the car on the left" gives cleaner results than both in one prompt.
Prompts that work (copy and adapt)
Google's tips for image prompts: start with action words like create or generate, name the style (photorealistic, watercolor, cartoon) and describe the subject and setting. For edits, add what must stay the same.
| Goal | Prompt |
|---|---|
| Clean background | "Replace the background with a plain light-gray studio wall. Keep the person, clothes and lighting exactly the same." |
| Remove an object | "Remove the trash bin on the right side. Fill the area so it matches the sidewalk." |
| Product photo | "Put this bottle on a white marble counter with soft morning light. Keep the label unchanged." |
| Style change | "Turn this photo into a watercolor painting, same composition." |
| Room makeover | "Repaint the walls sage green and add a wooden bookshelf on the left wall." |
| Combine photos | "Use the person in photo 1 and the beach in photo 2 to make one photorealistic image at sunset." |
| Text on image | "Add the words 'Grand Opening' in bold white letters at the top." |
The phrase "keep everything else the same" is the single most useful addition. Without it, Gemini may redraw more than you asked. If you're decorating, our guide on using AI to design a room goes deeper on interior prompts.
Nano Banana 2 vs Nano Banana Pro vs Lite
Gemini picks the image model from the Gemini model you have selected. Here's how Google's help page explains it:
| Model | When it's used | Good for |
|---|---|---|
| Nano Banana 2 Lite | Gemini model set to Flash-Lite | Quick images and basic ideas; not designed for multiple reference images or multiple edits |
| Nano Banana 2 | Gemini model set to Flash or Pro | Most edits; higher quality, reliable text, accepts multiple reference images |
| Nano Banana Pro | Paid Google AI plan, via More → Redo with Pro | Extra detail, text-heavy images and infographics |
So for editing, switch away from Flash-Lite before you start. Paid subscribers can take a Nano Banana 2 result and click Redo with Pro for more detail. Google notes that once you hit your daily Nano Banana 2 quota, you can't redo more images with Pro either.
Free vs paid: limits and quality
| Free Google account | Google AI plan | |
|---|---|---|
| Edit photos with Nano Banana 2 | Yes (18+) | Yes |
| Redo with Nano Banana Pro | No | Yes |
| Download resolution | 1K | 2K |
| Usage limits | Compute-based, refresh every 5 hours up to a weekly limit | Higher limits |
Google says Gemini's limits depend on the complexity of the prompt, the model and features used, and the length of the chat, and that images, music and video take a lot of that budget. Practical tip from the same page: start a new chat when you move to a new task, so a long chat doesn't eat your limit.

Connect Google Photos (US only)
If you're in the US, 18 or older and signed in with a personal Google account, you can connect Google Photos to Gemini and edit your library directly: Settings → Personal Intelligence → Connected Apps → Google Photos → Add. Google notes the connection isn't available in some US regions yet. With named face groups in Google Photos, Gemini can find the right people and pets for prompts like "make a claymation picture of me and my family."
Outside the US, simply download the photo and upload it to Gemini.
Rules, watermarks and honesty
- Age and terms: editing is 18+ and covered by Google's Terms of Service and Prohibited Use Policy. Don't edit photos of other people in ways they wouldn't agree to, and respect copyright.
- SynthID: Google uses invisible SynthID watermarks to identify images generated or edited by its AI. Anyone can upload an image to Gemini and ask "Was this created or edited by Google AI?"
- Disclose AI edits where it matters. A product photo with a changed background is fine for a shop banner; a "real" photo of an event that never happened is not.
Selling designs or digital products made this way? A simple storefront plus email list on systeme.io is a free way to start. And for designing graphics around your edited photos, Canva is the usual next step.
FAQ
Is Gemini photo editing free?
Yes, on a free Google account you can edit photos with Nano Banana 2 if you're 18 or older, within Gemini's usage limits. Paid Google AI plans add Nano Banana Pro, higher limits and 2K downloads.
Why does Gemini say it can't edit my image?
Common reasons: you're signed out, your account is under 18 or a school account with restrictions, the request breaks Google's usage policy, or you're on Flash-Lite (Nano Banana 2 Lite isn't designed for multiple edits). Sign in, switch to Flash or Pro, and rephrase the request.
How do I keep the person's face the same?
Say it in the prompt: "Keep the person's face, hair and expression exactly the same." Nano Banana 2 is designed for character consistency, but explicit instructions help.
Can Gemini edit photos on my phone?
Yes. Use the Gemini app on Android or iPhone, or gemini.google.com in a mobile browser. Upload the photo, tap Chat and type your edit.
What resolution do Gemini edited photos download at?
Google says 1K without a Google AI plan and 2K with one.
