How it works

1. Detect Position

Scans the bottom-right corner with both 48×48 and 96×96 masks at pixel-accurate 1 px steps. The position scoring compares sparkle-core brightness against surrounding background pixels — robust to dark or bright images.

2. Reverse Alpha Blending

Uses the real Gemini alpha maps from open-source reference PNGs. For each sparkle pixel: original = (px − α) × 255 / (255 − α)

3. 100% Private

All processing happens entirely inside your browser using the Canvas API. Your images are never uploaded to any server — complete privacy guaranteed.
