How Gemini Watermark Removal Works
1. Understanding Google's Visible Watermark
Google adds a visible 'Gemini sparkle' watermark to all Nano Banana and Nano Banana Pro images for free and Google AI Pro tier users. This watermark uses alpha blending: watermarked = alpha × logo + (1 - alpha) × original.
2. Automatic Watermark Size Detection
Our tool automatically detects the Gemini watermark size based on your image dimensions. Images larger than 1024×1024 use 96×96 watermarks, smaller images use 48×48 watermarks.
3. Mathematical Precision Removal
Using pre-calculated alpha maps from the Gemini sparkle pattern, we apply reverse alpha blending to mathematically recover the original Nano Banana generated image without the visible watermark.
