How does Reverse Alpha Blending remove Gemini watermarks without blur?
Traditional AI inpainting guesses and repaints missing pixels, which creates soft edges and blur. Google Gemini applies its watermark as a transparent mathematical overlay. Our tool reverses this linear compositing formula to mathematically recover the exact original background pixels underneath.
