Google AI Studio Watermark Remover
Remove Nano Banana watermarks from Google AI Studio images — free, instant, and 100% private. No registration required.
What is the Nano Banana watermark?
Google AI Studio (aistudio.google.com) applies a watermark called "Nano Banana" to all AI-generated images. Like the standard Gemini watermark, it is applied using alpha compositing — a deterministic mathematical operation. CleanMark reverses this operation exactly, recovering the original pixel values without any quality loss.

Why CleanMark Works So Well on AI Studio Images
Mathematically Exact
We reverse the exact alpha compositing operation Google uses — not an AI guess, not an approximation. Every affected pixel is restored to its original value.
Zero Quality Loss
No re-encoding, no compression. The output image has the same resolution, color profile, and sharpness as the original AI Studio output.
100% Private
All processing runs in WebAssembly inside your browser. Your images never leave your device — not even to our servers.
Under 1 Second
No AI model to run, no server round-trip. Pure math in WebAssembly completes in milliseconds regardless of image size.
FAQ
Does the Chrome extension work on AI Studio automatically?
The Chrome extension currently supports automatic watermark removal on gemini.google.com. For AI Studio images, use the online tool: download the image from AI Studio, then upload it to cleanmark.org/gemini-watermark-remover. Automatic AI Studio support is planned for a future release.
Is the Nano Banana watermark the same as the Gemini watermark?
They use the same underlying technique — alpha compositing — but are applied on different platforms. CleanMark handles both using the same reverse alpha blending algorithm.
Is my AI Studio image data safe?
Yes. All processing happens locally in your browser. Your images are never uploaded to any server.
Does it work on all AI Studio image types?
Yes — JPG, PNG, and WebP are all supported, at any resolution. The removal is based on the watermark pattern, not the image content.
