Frequently Asked Questions

The tool uses reverse alpha blending, not AI. Gemini adds its sparkle watermark using a fixed transparency formula. By knowing the exact alpha map, the tool mathematically reverses the formula to restore the original pixels with zero quality loss.

Yes, for original Gemini PNG exports. The reverse formula precisely recovers the original pixel values. Quality may degrade slightly if the image was recompressed by social media or saved as a screenshot.

Gemini uses two watermark sizes: 48x48 pixels for smaller images (both dimensions under 1024px) and 96x96 pixels for larger images. The tool auto-detects the correct size.

No. This tool only removes the visible sparkle watermark in the bottom-right corner. SynthID is an invisible watermark embedded in the frequency domain and requires different techniques.
