Yes. BanaGen is a free platform powered by Google's Nano Banana AI. Sign in with your Google account and get 24 free credits instantly — no credit card needed.
BanaGen supports all three generations of Google's Nano Banana AI: the original Nano Banana (Gemini 2.5 Flash), Nano Banana Pro (Gemini 3 Pro), and the latest Nano Banana 2 (Gemini 3.1 Flash). Each model offers different speed and quality tradeoffs — BanaGen lets you choose which one to use.
Yes, that's the primary workflow. Type a description of what you want, choose your preferred Nano Banana model (original, Pro, or Nano Banana 2), set style and resolution, and BanaGen generates a high-quality image in seconds. Nano Banana 2 is particularly strong at following detailed prompts and rendering accurate text within images.
Yes. BanaGen supports image-to-image editing — upload any photo and describe the changes you want. You can adjust lighting, change backgrounds, swap styles, add or remove elements, and more, all through natural language instructions.
BanaGen supports a wide range of styles including anime and manga, photorealistic portraits, fantasy and concept art, Pixar-style 3D renders, oil paintings, infographics, and more. You can specify styles directly in your prompt, or use one of the specialized tools in the app.
BanaGen generates images natively at up to 2K resolution and supports 4K upscaling for sharper, print-ready output. Resolution options and aspect ratio can be set before generating.
Each image generation costs 12 credits. New accounts receive 24 free credits on first sign-in — enough for two full generations. Subscription credits reset monthly; one-time credit packs never expire. You can see your balance at any time in the dashboard.
There's no hard daily limit — it depends on how many credits you have. Free credits (24 on signup) can be used at any time. Once they're gone, you can purchase a credit pack or subscribe to a Pro plan for ongoing access.
Yes. BanaGen is fully responsive and works in any modern mobile browser — Safari, Chrome, Firefox. No app download is required. Text-to-image and image-to-image both work on mobile without any loss of functionality.
On any paid plan, you own full commercial rights to every image you generate — including use in advertising, merchandise, and client deliverables. Images created using free credits are covered by a non-commercial license (CC BY-NC 4.0).
You do. BanaGen does not claim ownership of generated images. On paid plans, images are yours to use commercially. On the free tier, usage is personal and non-commercial. We recommend keeping a local copy of any image you intend to use.
Uploaded reference images are temporarily stored to process your generation request. They are not used to train AI models and are automatically deleted after a short retention period. We do not share your uploads with third parties.
By default, generated images may appear in the public gallery to inspire other creators. Pro plan users can enable Stealth Mode to keep their images entirely private — hidden from the feed and visible only to them.
We offer a 7-day refund on new subscriptions if you've used fewer than 50 credits. Email support@banagen.com with your order ID and we'll process it promptly. Note that payment processor fees are non-refundable in some regions.
