Blur the background, keep the subject sharp

Give any photo the soft background of a portrait-mode camera. The AI finds the person, pet or product on this device.

The first time, your browser downloads the AI model, about 170 MB. It is kept for next time, so later photos start straight away.

Add a photo, choose how soft the background should be and download the result. Nothing is uploaded.

How it works

A segmentation model finds the main subject of the photo, such as a person, a pet or a product. Everything else is blurred, while the subject is kept exactly as it was. The blur is worked out so the subject's colours do not bleed into the background, which keeps the edges clean.

Tips

  • Photos with one clear subject work best, such as portraits, product shots and pets.
  • A strength around 10 to 20 looks like a real camera lens. Higher values make the background a soft wash of colour.
  • Raise the edge softness if the outline of the subject looks too sharp.

Private by design

The AI runs inside your browser using your graphics card through WebGPU, which current Chrome, Edge and Safari support. Your photos are never sent to a server, and there are no credits, watermarks or sign-up.
