About This Tool
This Gemini watermark remover tool is provided for educational purposes only. It demonstrates the mathematical concept of reverse alpha blending, showing how Gemini AI watermarks applied through alpha compositing can be theoretically reversed. The algorithm is based on the open-source Gemini Watermark Remover project by journey-ad, which itself is a JavaScript port of the original Gemini Watermark Tool by Allen Kuo.

FAQ
Does this work on all AI watermarks?
No, this tool is specifically designed for Gemini AI watermarks only. Other AI services use different watermarking techniques.
Is there any quality loss?
No. The algorithm mathematically reverses the Gemini watermark blending, restoring the original pixels losslessly.
Is my image uploaded anywhere?
No. All processing happens in your browser. Your Gemini images never leave your device.
Why doesn't it work on my image?
The image must be directly from Gemini AI without any edits. Cropping, resizing, or re-saving can break the Gemini watermark pattern.
What is this tool for?
This Gemini watermark remover is for educational purposes only, demonstrating mathematical image processing concepts. Users are responsible for their own usage.
