Nano Banana is Google's newest image generation model, integrated into Gemini. It ships the same diamond sparkle watermark as every other Gemini export — and this tool strips it in seconds, entirely in your browser.

Nano Banana is the nickname for Google's latest image generation model. Under the hood it is still part of the Gemini family, and every output carries the same visible diamond sparkle in the bottom-right corner — exactly the same logo, in exactly the same position, at exactly the same sizes (48×48 for older exports, 96×96 for newer ones). That means the algorithm and alpha maps built for Gemini work on Nano Banana unchanged.
If you have a Nano Banana PNG and you upload it to this tool, the detector sees the same watermark it sees on Gemini, Imagen, and any other Google AI image. There is no special case to handle.

Clean first, then edit. Faster than Content-Aware Fill.
Google's watermark pipeline is shared across the image models. Whether the image comes from Gemini 1.5, Gemini 2.0 Flash, Imagen 3, Imagen 4, or Nano Banana, the alpha-blend math is identical. That is why one tool can clean them all — and why competitors that rely on AI inpainting (which guesses what should be under the logo) tend to smear the edge. Reverse alpha blending recovers the original pixels exactly.
