Blur the background of a photo

Add a portrait-mode look to any photo of a person. An on-device AI model finds the subject, keeps them sharp and blurs everything behind them — with adjustable strength and edge softness.

Why use this tool

On-device AI subject detection

A MediaPipe segmentation model runs in your browser to separate the person from the background.

Adjustable blur

Go from a gentle soft-focus to a strong bokeh effect.

Soft, natural edges

Edge feathering avoids a cut-out look around hair and shoulders.

Private by design

Your images are processed in your browser and never uploaded to a server.

Frequently asked questions

Good to know

  • Works best on portraits and selfies — the model is trained to find people.
  • The first run downloads a small AI model (~15 MB); after that it's cached.
  • Raise edge softness if hair looks cut out.
