  • Uses a people-only segmentation model, not a general product or object cutout model. Model-loading failures stop without producing a replacement cutout.
  • This is best for portraits; complex scenes are less reliable.
  • Works best for centered subjects with clear foreground/background separation.

Overview

Add portrait background blur in your browser

Create a depth-style background blur around a centered subject using browser canvas and a portrait mask. The result is best for clear portraits; complex hair, hands, or overlapping objects can reduce edge accuracy.
