About Gemini Watermark Remover
Overview
The Gemini Watermark Remover removes supported Gemini AI image watermarks directly in your browser. It uses the open-source Gemini watermark removal engine from GargantuaX/gemini-watermark-remover, which targets known Gemini watermark placement and reverses the watermark alpha blend instead of sending your image to a server or using generic AI inpainting.
Features
- Runs entirely in the browser so images never leave your device
- Uses a deterministic reverse alpha-blending watermark engine for supported Gemini outputs
- Supports drag and drop, file picker uploads, and clipboard paste
- Shows removal metadata such as pass count, decision tier, and detected watermark size when available
- Exports cleaned images as PNG, JPEG, or WebP
How to Use
- Upload, drag and drop, or paste a Gemini-generated image with a visible Gemini watermark
- Choose your output format: PNG, JPEG, or WebP
- Click "REMOVE GEMINI WATERMARK" to process the image locally in your browser
- Review the before and after preview, then download the cleaned image
- Use Clear to remove the current image and start again
FAQ
Are my images uploaded anywhere?
No. The image is decoded and processed locally in your browser. The tool does not upload your image to a server.
Does this remove every watermark?
No. It is designed specifically for supported Gemini AI image watermarks. It is not a general-purpose watermark remover.
Why did the tool say no watermark was applied?
The engine may skip processing when the uploaded image dimensions or detected watermark region do not match supported Gemini watermark patterns.
