How to Use Nano Banana for Free (and When It Isn't Free)

Yes, you can use Nano Banana for free, and the free version Google itself runs is Nano Banana 2 inside the Gemini app. Sign in with a Google account at gemini.google.com or in the Gemini mobile app, open the Create images tool, then type a prompt or upload a photo to edit. Without a paid plan you download images at 1K, every image carries a visible watermark plus an invisible SynthID mark, and your allowance refreshes every 5 hours up to a weekly limit. Google doesn't publish a number of free images per day.

As of September 23, 2026, three things are not free: Nano Banana Pro (it needs a Google AI plan), the Gemini API (no Nano Banana model has a free tier), and the credit packs sold by "Nano Banana" websites. Google AI Studio and Flow sit in between. Whether they make images for you without payment depends on your account, and each one tells you clearly when it wants money.

Which Nano Banana is the free one?

"Nano Banana" can mean Google's original image model or the whole family of image models Google now sells under that name. The one you get for free is Nano Banana 2.

A few details change what you should pick:

• Nano Banana 2 is the default. In the Gemini app, it handles your image request whenever Gemini is set to Flash or Pro. Google's image help page says it accepts multiple reference images and renders text more reliably than Lite.
• Lite is for speed. Google says Nano Banana 2 Lite can make an image "in as little as four seconds" (Google Cloud announcement, July 2026). In the Gemini app it isn't designed for multiple reference images or for several rounds of edits, so switch Gemini back to Flash for editing work.
• Pro only appears as a redo. In the app, Nano Banana Pro regenerates an image you first made with Nano Banana 2 or 2 Lite, and only for Google AI plan subscribers.
• The original model is going away. Google's pricing page says gemini-2.5-flash-image shuts down on October 2, 2026. Any tool still built on it has to move to Nano Banana 2 or 2 Lite.
• There is no Nano Banana 3 from Google. A site offering "Nano Banana 3" for free is using the name, not a Google model.

If you're still choosing between the three current models, Gemini Image Models in 2026: Lite, Nano Banana 2, or Pro? compares them by task.

Every free option, and where each one stops

The Gemini app is the only place where Google spells out what free users get: the model, the download size, and how the allowance works. The other options either cover narrower tasks or depend on your account.

Search is the easiest to overlook. Google's Nano Banana 2 launch post (February 26, 2026) says the model runs in AI Mode and Lens through the Google app and in mobile and desktop browsers, so you may be able to create an image straight from a search. What you see there depends on your country and language, and Google doesn't document download sizes or limits for Search the way it does for the Gemini app.

How to use Nano Banana 2 for free in the Gemini app

You need a personal Google account, a country where the Gemini app is offered, and to be old enough for the feature. The United States is on Google's list of more than 230 supported countries and territories. Editing images requires you to be 18 or older. Google's pages disagree on the age for generating: the help page says 13 (or your country's minimum), while the Gemini overview page says 18.

Create an image

1. Go to gemini.google.com or open the Gemini app on your phone, and sign in.
2. Choose Create images from the tools menu. On the web, you can also click Open Sidebar, then Images, and start from a template.
3. Keep the Gemini model on Flash or Pro if you want Nano Banana 2. Flash-Lite switches you to Nano Banana 2 Lite.
4. Describe what you want: the subject, what it's doing, the setting, and a style such as "watercolor" or "photorealistic." Then submit.

Edit a photo you already have

1. Upload the image in a chat, or open Library on the web and pick an image you generated earlier.
2. Say exactly what should change and what should stay the same, for example "replace the background with a beach at sunset, keep the person and the lighting on their face."
3. To combine ideas, upload several photos in one request and describe the new image you want.

Download and check what you got

Hover over the image and click Download full size. Without a Google AI plan, "full size" means 1K, even though the preview may look sharper. With a plan, the download is 2K. The file has a visible mark labeling it as AI-generated and an invisible SynthID watermark. Google doesn't say that any Gemini app plan removes the visible mark, so don't count on a subscription to remove it.

How many images can you make for free?

There is no fixed number, and any "X images a day" figure is not something Google publishes. According to Google's usage limits page, Gemini app limits are compute-based:

• Your allowance refreshes every 5 hours until you hit a weekly limit.
• Image generation uses more of it than a text chat. Google also says more advanced models and higher thinking levels consume more.
• Paid plans get multiples of the free limit: Google AI Plus is 2x the standard limit and Google AI Pro is 4x.
• Free accounts may be limited first when demand is high, and Google says limits "may change without notice." The page announced changes to limits starting May 17, 2026.

To see where you stand, go to gemini.google.com and select Settings, then Usage Limits (bottom left). The app warns you when you're close to your limit. When you reach it, the notice tells you when the limit refreshes.

One consequence matters if you plan to upgrade for Pro. Google's help page says that once you reach your daily quota of Nano Banana 2 images, you can't redo more images with Nano Banana Pro either. A paid plan raises the ceiling, but Pro redos stop whenever your Nano Banana 2 allowance does.

Which free option fits what you're making?

• Quick edits on your phone (a new background, a different hairstyle, a meme): use the Gemini app with Flash selected. It's free and handles edits and multiple reference photos.
• Rough ideas you'll throw away: if your account offers Flash-Lite, select it to get Nano Banana 2 Lite, which Google built for speed. Switch back to Flash when you start refining.
• Posters, invitations, or infographics with words on them: start with Nano Banana 2 in the Gemini app, since Google says it renders text better than Lite. If the lettering still comes out wrong and you need Pro's text handling, that's the point where free ends, because Redo with Pro requires a plan. Nano Banana 2 vs Pro: Which Should Be Your Default? covers when Pro is worth it.
• Files larger than 1K: no Google option guarantees this for free. The Gemini app gives 2K only with a plan, and 4K output means AI Studio or the API, which normally need billing.
• Building an app or script: the Gemini API has no free tier for any Nano Banana model, so budget from the first image. AI Studio may let you test prompts before you pay, depending on your account.
• Storyboards or video work in Flow: try opening Flow with your account. If it asks you to subscribe, Flow isn't free for you.
• You're outside a supported country: check which Google product is blocked before trying anything else. Gemini Isn't Available in Your Country? Check the Product Before the Fix walks through that.

AI Studio: free to open, not always free for images

Google's pricing page says "Google AI Studio usage is free of charge in all available regions." The same page lists every Nano Banana model with its free-tier price as "Not available." Google's billing page explains the gap: the free tier covers "certain models," and AI Studio stays free "unless users link a paid API key for access to paid features." Google doesn't say which image models run in AI Studio without billing, so the answer depends on your account.

The signal is simple. If AI Studio asks you to set up billing or connect a paid API key when you pick a Nano Banana model, image generation there isn't free for you. Moving to the paid tier means linking a billing account and prepaying at least $5 in credits.

Before you upload personal photos, know how Google treats unpaid use. The pricing page marks free-tier content as "used to improve our products," and under Google's Gemini API terms, content from unpaid use can be reviewed by people outside the EEA, Switzerland, and the UK. For more on what the free API tier includes, see Gemini API Free Tier in 2026: What Is Free and What to Check.

Flow: check your own account

Google Flow is a filmmaking tool, but it also generates images. Google's pages contradict each other on free access. The Flow credits page says that "with or without a subscription, you receive 50 Google Flow credits per day," and that non-subscribers can still generate images during peak hours. The Flow get-started page lists a Google AI Plus, Pro, or Ultra subscription as a requirement, along with being 18 or older and in a supported region.

If Flow opens for your free account, two details help. Failed generations aren't charged credits. In the US, the visible watermark is a toggle under your profile picture, while SynthID stays on every output. Flow may also slow you down with "You're requesting generations too quickly," especially on zero-credit models.

How to tell if a "Nano Banana" site is actually Google's

Many sites use "Nano Banana" in their domain name and describe themselves as a free Nano Banana editor. Google's own Nano Banana tools live at these addresses:

• gemini.google.com and the Gemini app for Android and iPhone
• gemini.google for Google's product overview pages
• google.com for Search AI Mode and Lens
• aistudio.google.com for AI Studio
• Google Flow, which you can reach from the links on Google's Flow help pages

Anything else is a third party, no matter what its logo or headline says. Those sites typically give a small number of free credits and then sell their own plans. From the outside you can't tell which model they call, what they do with uploaded photos, or who runs them. A few quick signs:

• They sell credit packs or ask for a card before or right after your first images. The Gemini app's free allowance needs no payment details.
• They promise "no watermark" on free output. The Gemini app adds a visible mark, and all Nano Banana images carry SynthID.
• They offer "Nano Banana 3" or another version Google hasn't announced.
• They name gemini-2.5-flash-image or "Gemini 2.5 Flash Image" as their model. That model shuts down on October 2, 2026, so the site has to switch.

If you still want to try one, don't upload photos of people who haven't agreed to it, and don't reuse a password from your Google account.

When the free allowance runs out

What to do next depends on which limit you hit.

The Gemini app says you've reached your limit. The notice tells you when it refreshes. If waiting a few hours is fine, that's the free answer. If you keep hitting it, a Google AI plan raises the limit (Plus 2x, Pro 4x), switches downloads to 2K, and adds Redo with Pro. Google lists current plan prices on its subscription page.

AI Studio asks for billing, or you need an API. You're now on pay-per-image pricing. Google's standard rates for image output, as of September 23, 2026:

These are output prices only. Input tokens, text and thinking tokens, and Search grounding are billed separately, and the Batch API costs roughly half. As a worked example, 200 images from Nano Banana 2 at 2K cost 200 × $0.101 = $20.20 in output at standard rates, or 200 × $0.050 = $10.00 through Batch. Nano Banana Pro API Pricing: 1K, 2K & 4K Costs goes deeper on Pro, and Nano Banana API Troubleshooting: 400, 429, 503, NO_IMAGE, Timeouts helps once you're calling the API.

You want 2K or 4K files without setting up Google Cloud billing. YingTu is a paid browser image studio that calls the Gemini API with a LaoZhang API key. As of September 23, 2026, it lists Nano Banana 2 at a reference price of $0.055 per call for any resolution up to 4K, and it also offers Nano Banana 2 Lite and Pro. Each output image is a separate charged call, and the site says to confirm actual pricing in your console. At that reference price, 200 Nano Banana 2 images would be 200 × $0.055 = $11.00. That's below Google's standard 1K, 2K, and 4K rates for Nano Banana 2, though not below Google's Batch rate at 2K. It isn't free, and it's worth it only if you need larger files or API-style access without Google's billing setup.

Quick answers

Is Nano Banana 2 free?

Yes, in the Gemini app without a paid plan, within an allowance that refreshes every 5 hours up to a weekly limit. Downloads are 1K with a visible watermark. It is not free through the Gemini API, where Google lists no free tier for it.

Can I use Nano Banana Pro for free?

Not through Google. In the Gemini app, Pro is available only as "Redo with Pro" for Google AI plan subscribers, and the API charges $0.134 per 1K or 2K image. Sites advertising free Pro access are third parties with their own credit limits.

Is there a free Nano Banana API?

No. As of September 23, 2026, Google's pricing page lists the free-tier price for every Nano Banana model as "Not available." AI Studio may let some accounts test image prompts without billing, but that isn't an API allowance you can build on.

Is Nano Banana 3 out?

No. Google hasn't announced a Nano Banana 3. The current models are Nano Banana 2, Nano Banana 2 Lite, and Nano Banana Pro, and the original Nano Banana shuts down on October 2, 2026.

Can I remove the watermark for free?

Not in the Gemini app, which adds a visible watermark to images, and Google doesn't say a paid plan removes it. Flow has a visible-watermark toggle in the US if your account can use Flow. Every Nano Banana image keeps the invisible SynthID mark, and you can upload an image to the Gemini app and ask whether Google AI made it.
