Gemini Watermark Remover AI - Remove Watermark From Gemini, Nanobanan
Gemini Watermark Remover — Free Online Tool by Quick Image Fix
Remove the Gemini star watermark (also known as the Nano Banana logo) from AI-generated images instantly — directly in your browser, with no signup, no server uploads, and no usage limits.
Unlike most watermark removal tools that rely on AI inpainting to guess what's underneath, this tool uses reverse alpha compositing — a precise mathematical reversal of the exact formula Google uses to apply the Gemini watermark. The result is pixel-perfect restoration with an error margin of just ±1 per channel, completely invisible even at 100% zoom. No smearing, no artifacts, no hallucinated texture.
How it works in 3 steps:
- Upload your Gemini-generated PNG, JPG, or WebP image (batch upload up to 10 files at once)
- The tool auto-detects which watermark variant your image uses (48×48 or 96×96 pixels) and applies the reverse formula locally in your browser
- Download your clean image in under 100ms — individually or as a ZIP
Key features:
- ✅ 100% browser-based — all processing runs via JavaScript Web Workers; images never leave your device
- ✅ No account or signup required — free forever with no hidden limits
- ✅ Batch processing — handle up to 10 images simultaneously
- ✅ Auto-detection — automatically identifies the correct watermark size to prevent color fringing
- ✅ Multiple output formats — export as PNG, JPEG, or WebP with adjustable quality
- ✅ Works on all devices — iPhone, Android, and all major desktop browsers (Chrome, Firefox, Safari, Edge)
- ✅ Google AI Studio compatible — handles both Gemini.google.com and AI Studio (aistudio.google.com) outputs identically
