Gemini Watermark Remover

Gemini Watermark Remover is a free, browser-based tool that removes the visible Gemini logo from AI-generated images without uploading anything. Instead of cropping the corner or using AI inpainting, it reverses the exact alpha-blend math Gemini applies when stamping its logo, restoring the original pixels underneath pixel by pixel. Detection and removal run entirely on your device — you can switch to airplane mode after the page loads and it keeps working, and closing the tab removes every trace. There's no sign-up, no credits, no daily cap, and no server involved. The tool is touch-friendly for phones, supports batch processing with ZIP download, and handles both older and newer Gemini watermark placements automatically. It's aimed at anyone who generates images with Google Gemini and wants clean copies for printing, sharing, or use in projects — without the corner logo getting in the way. Note that it only removes the visible logo; the invisible SynthID signal embedded in the pixels stays intact, so the image remains identifiable as AI-generated by software that checks for it.
