Image Diff

Design review and UI regression work often starts with two screenshots. Image Diff normalizes them to a shared canvas, highlights changed pixels and reports the changed ratio.

Images are normalized to a shared canvas. This is useful for UI regression and design review, not perceptual image quality scoring.

FAQ

Is this perceptual diff?
No. It is a fast pixel-level diff for visual review, not a perceptual metric.
