How it works

How to use Blur Background online

  2. Adjust blur strength, subject size, feathering, format, and quality settings.
  3. Run the effect in your browser, inspect the edges, and download the image.

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.
