Frequently Asked Questions

Is NanoBanana free to use?
Yes, NanoBanana is completely free with no registration or payment required.
Are my images uploaded to a server?
No. All processing happens entirely in your browser. Your images never leave your device, ensuring complete privacy.
Does it reduce image quality?
No. NanoBanana uses reverse alpha blending to mathematically restore the original pixels, resulting in zero quality loss.
What image formats are supported?
NanoBanana supports PNG, JPG, and WebP image formats.
How does the watermark removal work?
Gemini embeds watermarks using alpha compositing. NanoBanana captures the watermark pattern on a known background, reconstructs the exact alpha map, and applies the inverse formula to restore original pixels with zero loss.
