Gemini Watermark AI is a browser-based tool that removes the visible Gemini sparkle watermark from AI-generated images and videos. It is built for content creators, designers, marketers, social media managers, and small business owners who want clean, professional visuals for their own projects, such as presentations, campaigns, product listings, and social posts. The tool uses reverse alpha blending to restore the pixels under the logo, rather than cropping, blurring, or guessing with AI inpainting. This keeps the original resolution and quality intact. All processing happens locally in the user’s browser, so files are never uploaded to a server, which protects privacy and means no account is required. It supports PNG, JPG, and WebP images and MP4, MOV, and WebM videos, with batch processing for multiple files. It works with content from Gemini, Google Flow, Veo, Imagen, and Nano Banana.
