How It Works — Reverse Alpha Blending
No AI inpainting or guessing. Gemini watermarks are blended with a known alpha channel, which can be mathematically inverted for a perfect, lossless restoration.
Core formula
original = (watermarked − α × logo) / (1 − α)
Since the watermark's alpha map is known, the original pixel value can be computed exactly — producing lossless results impossible with AI inpainting.
