If you've generated an image with Google's Nano Banana model and want to remove the diamond watermark, you're in the right place. This tool is a dedicated Nano Banana watermark remover — built specifically to handle the visible diamond logo that appears on every free-tier Nano Banana image.
Unlike generic AI inpainting tools that guess what's under the watermark, this tool uses the exact reverse of Nano Banana's watermark algorithm. The result is pixel-perfect: zero quality loss, no blurring, no artefacts. Just your original image without the diamond watermark.
Nano Banana is Google's latest image generation model, built into the Gemini AI assistant. It's the successor to Google's earlier Imagen models and represents a significant step up in image quality, text rendering, and prompt understanding.
If you've used Gemini to generate images recently, you've almost certainly been using Nano Banana — even if you didn't know the name. Google integrated it into Gemini as the default image generation engine, replacing the previous version.
The name is a bit unusual (Google has a history of quirky internal codenames), but the model itself is seriously capable. It handles photorealistic imagery, artistic styles, text within images, and complex compositions better than previous versions.
The one thing that hasn't changed? The watermark. Every Nano Banana image still comes with that same diamond logo in the corner, plus the invisible SynthID watermark in the pixel data. Our tool handles the visible one.
If you've been searching for a “Nano Banana watermark remover” specifically — you're in the right place. Nano Banana uses the exact same diamond watermark that all previous Gemini image generation models used.
The watermark is applied using the same alpha blending algorithm. The watermark mask images (the 48x48 and 96x96 pixel diamond logos) are identical. The placement logic is the same. This means our Reverse Alpha Blending removal algorithm works perfectly on Nano Banana images — no modifications needed.
Whether your image was generated by the original Gemini, Gemini Pro, Gemini Ultra, or the latest Nano Banana model, the watermark removal process is identical. This makes it a universal AI diamond watermark remover for the entire Gemini / Nano Banana ecosystem. Drop your image, get a clean version. That's it.
Drag and drop your Nano Banana / Gemini image or click to select it from your device.
Our Reverse Alpha Blending algorithm mathematically removes the diamond watermark in milliseconds.

Nano Banana produces noticeably sharper, more detailed images with better colour accuracy and more natural lighting. The step up from earlier Gemini versions is significant.
One of the biggest improvements. Nano Banana is much better at rendering text within images — fewer misspellings, more consistent fonts, and better integration with the overall composition.
Complex, multi-part prompts are handled more accurately. Nano Banana is better at understanding spatial relationships, specific styles, and nuanced instructions.
Image generation is typically faster with Nano Banana, often under 10 seconds for standard requests. This makes rapid iteration even more practical.
Like previous versions, Nano Banana images are processed through Google's servers. The visible watermark and invisible SynthID are both still present on every generated image.
Nano Banana is available on the same free and paid Gemini tiers. Free users get the watermark. Ultra users ($20/month) get watermark-free output. Or use our free tool.
The Nano Banana diamond watermark is a small diamond-shaped logo that Google automatically places in the corner of every image generated by Nano Banana (Google's latest AI image model in Gemini). It's a visible watermark — you can see it clearly in the bottom-right corner of your image. Google applies it using alpha blending, which means it can be mathematically reversed and removed without any quality loss.
Upload your Nano Banana image using the tool at the top of this page. Our Reverse Alpha Blending algorithm detects the diamond watermark automatically and removes it in milliseconds — entirely inside your browser. No server upload, no account needed. Download the clean image for free at original resolution, or pay $2 to upscale it to HD print resolution.
Yes — removing the Nano Banana diamond watermark is completely free. Upload your image, wait a second for processing, and download the clean version. There is no account, no email, and no cost. The optional HD upscale (2x resolution using Clarity AI) costs $2 per image, but the standard watermark removal is always free.
Nano Banana is Google's latest image generation model, integrated into the Gemini AI assistant. It's the successor to the earlier Imagen models and produces higher-quality, more detailed images with better text rendering. Despite the new name, it uses the same diamond watermark as previous Gemini image generation.
No. Nano Banana uses the exact same visible diamond watermark as previous Gemini versions. The watermark algorithm hasn't changed, which means our removal tool works identically on both old Gemini and new Nano Banana images. Same watermark, same fix.
Yes. Like all Gemini image generation, Nano Banana embeds an invisible SynthID watermark in the pixel data. Our tool only removes the visible diamond logo — it doesn't touch SynthID. Most people only care about the visible watermark as that's the one that's distracting and looks unprofessional.
Nano Banana is available through Gemini's free tier as well as paid tiers (Pro and Ultra). The free tier includes image generation with the diamond watermark. Only the Ultra tier ($20/month) removes the visible watermark by default. Our tool removes it for free.
Google hasn't officially explained the naming. It's part of their tradition of giving internal project names that are memorable and slightly playful (like Android version names used to be). The model itself is a significant upgrade over previous Gemini image generation capabilities, regardless of the quirky name.
