Gemini 批量去水印工具｜Prompt Case

Gemini Watermark Remover is a browser extension built specifically for images generated by Gemini. It helps you quickly remove the “Gemini” watermark in the bottom‑right corner of Nano Banana, and Pro images in bulk while preserving the original image quality and details. ​ All processing is completed locally in your browser.

Just drag and drop your images to process them. Perfect for: - Designers, creators, and marketers who frequently use Gemini to generate assets. - Anyone who needs to use AI images in presentations, social posts, or commercial projects and wants a cleaner, more professional layout. After installation, click the Gemini Watermark Remover icon in your browser toolbar, then drag and drop or upload your Gemini images to instantly get new files with the watermark removed.

Gemini Watermark Remover — Banana Clean

Remove the Gemini watermark on download. Converts to WebP/JPEG, auto-renames files. Pixel-perfect, 100% local, under 100ms. Banana Clean removes the Gemini watermark from AI-generated images as you download them. It also converts images to WebP or JPEG — cutting file size by 75% — and auto-renames files to clean, dated names. Features that other watermark removers don't offer. How it works: 1. Generate an image on gemini.google.com or Google AI Studio. 2. Click the download button. 3. The extension intercepts the file, removes the Nano Banana sparkle logo using reverse alpha blending, converts to your chosen format, and renames the file. All in under 100 milliseconds. What you get: - Pixel-perfect watermark removal. Reverse alpha blending restores original pixels instead of blurring over them. No inpainting artifacts. - Format conversion on download. Save as WebP (~2 MB) or JPEG (~1 MB) instead of the default 8 MB PNG. Pick your format in the popup. - Crop presets for social media (PRO). One click to save in Instagram Square, Feed Portrait, Stories/Reels, YouTube Thumbnail, or Pinterest Pin size. Or set a custom size. - OMNI Video cleanup for supported Gemini MP4 files (PRO). Looks for the visible sparkle mark, cleans it when detected, and keeps the audio. If no mark is found, the file is saved as is. - Auto file renaming. Saved files get clean names like gemini-2026-04-11-001.webp instead of random hashes. - 100% local processing. Images never leave your browser. No uploads, no accounts. - Under 100ms per image. You won't notice it running. Works with the built-in download button on gemini.google.com and Google AI Studio. Compatible with any Chromium-based browser. 15 free cleanups included. PRO: $2.99/month or $24.99/year (save 30%). Pay with credit card, Apple Pay, Google Pay, or Telegram Stars. Cancel anytime. Only the visible Nano Banana logo is removed. Invisible SynthID metadata remains intact.

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 image without 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 mathematically recover original pixel values 🖼️ 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 For bugs, email us at qazi.web@gmail.com
