The gist

Gemini Watermark Remover is an open-source tool by GargantuaX for removing the visible watermarks from AI-generated images and videos created by Google's Gemini. Instead of using unpredictable AI inpainting, the tool applies a mathematically precise Reverse Alpha Blending algorithm to losslessly restore the original pixels beneath the semi-transparent logo. It's designed to provide high-fidelity, reproducible results for supported Gemini outputs.

What it does

Removes visible watermarks from Gemini-generated images and videos.
Processes all media entirely locally in the browser or on your machine.
Uses a deterministic Reverse Alpha Blending algorithm for precise, lossless removal.
Automatically detects watermark size and position for known Gemini outputs.
Offers multiple interfaces including a web tool, Chrome extension, userscript, and CLI.

How it works

Gemini Watermark Remover Architecture Diagram

The tool works by applying a Reverse Alpha Blending formula to mathematically reverse the compositing process used by Gemini to add its watermark. Users can drag-and-drop an image or video onto the web tool, or use the browser extension which automatically processes images on the Gemini website. The tool is delivered as a free online utility, a browser extension, a userscript, a command-line interface, and an SDK. It is open-source and free to use.

Best for

This tool is best for users of Google Gemini who need to quickly and reliably remove the visible watermark from generated images or videos for a cleaner presentation.

Watch out for

The tool only removes Gemini's specific visible watermark and does not affect invisible watermarks like SynthID. Its effectiveness depends on Gemini's watermark pattern remaining consistent with what the tool supports.
