Gemini Watermark Remover

Gemini Watermark Remover is a free, open-source browser tool for removing the visible Gemini mark from JPG, PNG and WebP images. Instead of generative filling, it uses reverse-alpha blending to mathematically restore the pixels beneath the mark. Everything runs locally – no uploads or accounts. Process one image or a batch, compare before and after, then export at your preferred JPEG quality or copy a lossless PNG.
