About Gemini Watermark Fix
Free, private watermark removal for Gemini and Veo 3
Gemini Watermark Fix exists because removing a watermark from your own AI-generated image or video shouldn't require handing that file to a stranger's server. Every other "watermark remover" online asks you to upload your file first — Gemini Watermark Fix doesn't, because it doesn't need to.
Whether you search for a Gemini watermark remover, a Gemini logo remover, or just a Gemini remover, this is the same tool: it targets the small sparkle logo Gemini stamps onto generated images and videos, and removes it losslessly, on your own device.
Why it's local-only
Watermark removal here isn't AI guesswork run in the cloud. It's a deterministic mathematical technique called Reverse Alpha Blending: since a visible watermark is applied by blending a known logo over your image at a known transparency, that blend can be mathematically undone, pixel for pixel, using nothing but your own browser's JavaScript and WebAssembly engine. There's no cloud model to call and no reason to ever see your file on a server.
For video, the same reverse-blend runs frame by frame using WebCodecs, with a small local AI model (running entirely via ONNX Runtime Web, still on your device) polishing residual compression artifacts left behind after re-encoding.
What it supports today
- Gemini-generated images with the standard bottom-right visible watermark, at known output sizes.
- Gemini and Veo 3 generated videos with the same bottom-right watermark placement.
- JPG, PNG, WebP for images; MP4, WebM, and MOV for video, with MP4 output.
It does not remove invisible or steganographic watermarking schemes (such as SynthID) — those are a fundamentally different mechanism embedded in the pixel data itself, not a visible overlay, and are outside the scope of this tool.
