Banana Clean — Gemini & Nano Banana Watermark Remover

Automatically removes Gemini and Nano Banana watermarks when you download AI-generated images. 100% local, fast, private.

Banana Clean automatically removes the Gemini watermark and Nano Banana logo from AI-generated images as you download them. No uploads, no manual editing — the cleaned file saves directly to your computer. How it works: 1. Open gemini.google.com or aistudio.google.com and generate an image. 2. Click Download. 3. Banana Clean intercepts the file and restores the original pixels using reverse alpha blending — a mathematically precise method that reconstructs the image instead of blurring over it. Unlike online watermark removers that require you to upload each image, Banana Clean processes everything locally inside your browser. Your images never leave your device. What makes it different: - Runs automatically on every download — nothing to click or configure. - Pixel-perfect results in under 100ms. No blurry patches, no inpainting artifacts. - 100% private. Zero server uploads, zero accounts, zero data collection. - Minimal resource usage — you won't notice it running. Works with PNG images from the built-in download button on gemini.google.com and Google AI Studio. Compatible with any Chromium-based browser. 15 free removals included. One-time $4.99 PRO upgrade unlocks unlimited use — no subscriptions, no recurring fees. Only the visible sparkle logo is removed. Invisible SynthID metadata remains intact.
