Technical Specifications & How It Works
The color extraction algorithm uses spatial bucket quantization to group color frequencies and identify dominant brand palettes.
Pixel color data is sampled from 32-bit RGBA canvas buffers directly on your device CPU.
100% Client-Side Privacy: Your images never leave your computer or phone. Processing runs completely in local browser memory via WebAssembly and Canvas APIs. No file data, filenames, or metadata are ever transmitted.
