Gemini Watermark Remover

A lightweight browser extension that automatically removes the Gemini watermark from AI-generated images — silently, in real-time, before the image ever renders on the page.

How it works:
⭐ You just have to install the extension and download images from Google Gemini as usual, background removal will work on the background, and you will get an image without a watermark. ⭐

What It Does:
When you generate or view images on Gemini, Google overlays a semi-transparent watermark logo in the bottom-right corner of every image. This extension intercepts those images at the network level and mathematically reverses the watermark blending to recover the original clean pixels — all without re-requesting the image or affecting page performance.

Features:
🚫 Removes the Gemini watermark logo automatically from all generated images
⚡ Works in real-time — images are cleaned before they render on the page
🔁 Intercepts at the network layer by wrapping the native fetch API
🧮 Uses a reverse-alpha algorithm to recover original pixel values mathematically
🖼️ Handles both small (48×48) and large (96×96) watermark logo variants automatically
💾 Caches the logo alpha map so it's only decoded once per session
🛡️ Non-destructive — falls back to the original image if anything goes wrong
🔇 Completely silent — no UI, no popups, no notifications
🌐 Scoped exclusively to gemini.google.com — does not run on any other site
🧹 Cleans up automatically when you leave the page
