Nano Banana is Google's image model inside the Gemini app. Every image it creates gets the same small, white Gemini sparkle in the bottom-right corner. Our Gemini watermark remover detects that sparkle automatically and removes it, keeping your image at its original resolution.
How to remove a Nano Banana watermark
- Upload your Nano Banana image. Open the Gemini Watermark Remover and upload or paste the image you created with Nano Banana.
- Watermark removed automatically. The Gemini sparkle in the bottom-right corner is found and removed straight away.
- Download. Touch up with the brush if needed, then download the full-resolution PNG.
You can also drag the image straight onto the upload box, or paste it with Ctrl+V / Cmd+V.
Clean results, not a blurry patch
The Gemini sparkle is semi-transparent, so the picture underneath is still there. The tool finds the sparkle's exact outline and repairs only those pixels, rebuilding the background with matching texture from around it. Skies, skin, fabric and patterns carry on naturally instead of turning into a smudge.
- Full resolution: your image keeps its original size and detail.
- Instant: the sparkle is removed the moment the image loads.
- Touch-up brush: paint over anything left and it's erased when you let go.
- Private: images are processed on your device and never uploaded.
