Gemini (Nano Banana) Image Watermark Remover

This tool is designed specifically to remove watermarks from images generated by Google Gemini. Unlike typical AI retouching, it uses a “reverse alpha blending algorithm” to precisely recover the original pixels covered by the watermark, enabling true lossless removal.

Key features:

• Lossless restoration: Uses mathematical operations to accurately remove Gemini watermarks without blurring or inpainting, preserving original details.
• Ultra-fast processing: No queues—drag and drop to finish instantly.
• Privacy-first: Pure front-end processing ensures images never leave your device.
• Purpose-built optimization: Automatically detects current and legacy Gemini watermark sizes, positions, and alpha profiles.

How to use: Upload the original JPG/PNG image generated by Google Gemini (do not use screenshots, as they may damage pixel characteristics). The system will automatically detect and remove the watermark.
