Nano Banana Watermark: What It Is and How to Remove It

Nano Banana is the name Google uses for the watermark applied to AI-generated images in Google AI Studio (aistudio.google.com). If you've ever downloaded an image from AI Studio, it contains this watermark.

What Is the Nano Banana Watermark?

Nano Banana is Google's internal name for the AI Studio watermark. Like the standard Gemini watermark on gemini.google.com, it is applied using alpha compositing — mathematically blending a watermark layer with the original image.

Both use the same underlying technique, but are applied on different platforms:

• gemini.google.com: Standard Gemini watermark
• aistudio.google.com: Nano Banana watermark
