Remove Gemini watermarks, losslessly.
A mathematically exact Reverse Alpha Blending engine that restores the original pixels. No AI guesswork, no servers.
Drop an image or video. Clean it on this page.
Everything runs locally in your browser. Drag a Gemini-generated file below; nothing is uploaded.

Supports JPG, PNG, WebP for images, and MP4, WebM, MOV for video.
Precision where other tools hallucinate.
Most removers paint over the watermark with a generative model. This one solves the equation Gemini used to add it, then reverses it.
Reverse Alpha Blending
It reconstructs the underlying image by inverting the exact watermark compositing formula, pixel by pixel.
Fully local and private
Processing runs entirely in your browser or on your machine. No file ever leaves your device, so nothing is logged or stored.
Automatic detection
Finds watermark size and position from Gemini's known output catalog and a local anchor search.
Image and video
Clean still images or strip the watermark from Gemini-generated video, frame by frame.
Runs everywhere
Works across modern browsers and Node.js, as a site, extension, userscript, CLI, or SDK.
Three steps, zero guesswork.
Capture the alpha map
The watermark is profiled on a known background to recover its per-pixel opacity, so the math matches reality.
Solve the inverse blend
Each pixel in the watermark region is run back through the compositing equation to recover its true color.
Restore the original
Clean pixels are written back in place with numerical safeguards against noise and clipping.
Use it the way that fits your workflow.
One engine, five surfaces. Use it right here, or wire the SDK into your pipeline.
