A clear answer. Here’s how.

Counts every decoded pixel into 256 bins separately for red, green, blue and alpha. RGB plot shares one frequency maximum; CSV includes all four channel counts. RGB values under transparent pixels are included without compositing. This describes decoded display-channel codes, not raw sensor data, perceptual exposure or a colour-profile analysis. Supports PNG/JPEG/WebP up to 10 MB and 4 million decoded pixels per file. Browser decoding and single-frame PNG re-encoding remove source metadata/colour profiles; no files leave this device.
