How It Works
⚡ Quick Method (Alpha Blending)
- • Uses Reverse Alpha Blending algorithm for lossless watermark removal
- • Automatically detects watermark size (48×48 or 96×96) based on image dimensions
- • Mathematical precision - not AI guessing, perfect pixel restoration
- • Instant processing, no model download required
- • 💡 For best results, use the original image from Gemini. Thumbnails or resized images may not work perfectly.
🧠 AI Method (LaMa Inpainting)
- • Uses LaMa (Large Mask Inpainting) neural network model
- • AI reconstructs the area under the watermark based on surrounding context
- • Better for complex backgrounds or when alpha blending leaves visible artifacts
- • Requires one-time ~200MB model download (cached in browser)
- • Supports WebGPU acceleration when available
📋 General
- • 100% client-side processing - your images never leave your browser
- • Supports batch processing with ZIP download
⚠️ Disclaimer
- • This tool only removes visible Gemini watermarks (the semi-transparent logo in bottom-right)
- • Does not remove invisible/steganographic watermarks (SynthID)
- • Designed for Gemini's current watermark pattern (as of 2025)
- • Use responsibly and respect intellectual property rights

About Gemini Watermark Remover
A powerful tool for removing Gemini AI (Nano Banana) watermarks from generated images. Supports two methods: (1) Quick Alpha Blending - mathematically precise reverse alpha blending for instant, lossless pixel restoration; (2) LaMa AI - neural network inpainting for complex backgrounds. Features automatic watermark detection (48×48 or 96×96), before/after comparison, batch processing with ZIP download, and WebGPU acceleration. 100% client-side - your images never leave your browser.
