How It Works

Reverse Alpha
Blending Algorithm

Gemini applies watermarks using standard alpha compositing. We reverse the formula mathematically to restore the original pixel values with zero loss - no AI inpainting needed.

Gemini adds:

watermarked = α × logo + (1 - α) × original

We reverse:

original = (watermarked - α × logo) / (1 - α)
