Frequently Asked Questions
How does the Gemini Watermark Remover work without blurring?
Google Gemini embeds its 4-point sparkle watermark via standard alpha blending: Watermarked = Original * (1 - Alpha) + 255 * Alpha. Because the exact logo shape, size, and alpha transparency mask are known, our tool mathematically solves for Original = (Watermarked - 255 * Alpha) / (1 - Alpha). This achieves 100% mathematically exact pixel reconstruction without blurring or AI hallucination.
Are my images uploaded to your web server?
No. All processing is executed 100% on your device inside your web browser using HTML5 Canvas and Float32 typed arrays. Your files never touch our servers or any third-party cloud.
Does this work on Gemini, Imagen 3, and Google Flow images?
Yes! The tool is calibrated for all Google Gemini, Imagen 2, Imagen 3, Google Flow, and Nano Banana AI generated images.
Can I adjust the settings if my image was resized or cropped?
Yes. Under the Advanced Settings drawer, you can manually fine-tune the size scale, alpha intensity (gain), and horizontal/vertical position offsets (X/Y) to match any resized or modified image.
