Traditional watermark removers rely on deep learning inpainting models like Stable Diffusion or LaMa. These models do not know what was originally behind the watermark—they simply paint over the area by guessing surrounding textures, which frequently results in blurry spots, unnatural smudges, or altered details.
In contrast, Google Gemini and Imagen apply their visible watermark using digital alpha compositing:
Because the transparency coefficient (α) and logo color are mathematically fixed, promptvila solves the equation backwards:
This exact mathematical inversion recovers the genuine image pixels with zero loss of quality, sharp edges, and true colors.
No software installation or account registration required.
Drag and drop your Gemini-generated PNG, JPG, WebP image or MP4 video into the upload area or paste directly from your clipboard.
The engine automatically detects the watermark coordinates, applies Reverse Alpha Blending, and provides an interactive comparison slider.
Copy the cleaned result to your clipboard or download it in lossless PNG, WebP, or high-definition MP4 video format.
