About Gemini Watermark Remover
A browser-based tool for removing visible Gemini AI (Nano Banana) watermarks in generated images.

Frequently Asked Questions
What watermark types does this tool target?
It is designed for visible Gemini AI / Nano Banana-style watermarks in generated images. The detector uses known Gemini output patterns and local matching to estimate the watermark position and size automatically.
Does this use AI inpainting?
No. The tool uses reverse alpha blending to restore pixels from Gemini's visible watermark layer, so it avoids AI repaint blur around text.
Does watermark removal happen locally?
Yes. The workflow is client-side, so images are processed in your browser instead of being uploaded to a remote server.
