About This Tool
Images generated by Gemini have a transparent watermark in the bottom right corner. This tool restores the original pixels using a pre-extracted alpha channel and the reverse blending formula:
Original = (Watermarked - Alpha * Logo) / (1 - Alpha)
The tool supports two watermark sizes:
- 48x48 (for smaller images)
- 96x96 (for images larger than 1024px)
