Open Source Licenses

Gemini Watermark Remover removes watermarks inside your browser with open source software written by other people. We did not write the removal engine and we have not changed it; we only built the page around it. This page credits the authors, lists the licenses and links to the source.

The removal engine

• Gemini Watermark Remover by GargantuaX, npm package @pilio/gemini-watermark-remover 1.0.46. It finds the visible Gemini sparkle and reverses the alpha blending that put it there, for images and videos. License: MIT.
• It is a JavaScript port of Gemini Watermark Tool by Allen Kuo (allenk), who worked out the reverse alpha blending method and calibrated the watermark masks. License: MIT. His write-up: Removing Gemini AI Watermarks: A Deep Dive into Reverse Alpha Blending.
• The video cleanup pass uses the FDnCNN denoising model as exported by the Gemini Watermark Tool project (ONNX, MIT).

Libraries used by the video remover

• ONNX Runtime Web 1.26.0 by Microsoft, runs the denoising model in WebAssembly. License: MIT.
• Mediabunny, reads and writes the MP4 file. License: Mozilla Public License 2.0. It is used unmodified, bundled inside the engine above; its source is at the link.
