A blurred background mimics the depth-of-field look of a portrait lens: the subject stays sharp while everything behind them softens, removing distractions and drawing the eye. This tool separates the subject automatically, then blurs the original background by an amount you control — no expensive lens or photo editor required.
Blur background: how it works
- What you get
- A PNG where the subject stays fully sharp while the original background is softened, for a portrait-style depth-of-field look.
- How it runs
- The ISNet model separates the subject, then the original photo is blurred on a canvas and the sharp cut-out is drawn back on top. A slider controls the blur strength, so the same shot can go from a gentle softening to a heavy, creamy background.
Best for
- Portraits and headshots that need a flattering, less busy backdrop
- Video-call and webinar profile shots
- Product or food photos that should pop from the scene
- Faking a wide-aperture lens look without one
Practical tip
Because the real background is blurred (not removed), this keeps colours and lighting that match the subject, which usually looks more natural than a solid fill. Push the blur too far and the boundary around the subject can look slightly cut-out, so a moderate amount is often the most convincing.
Blur background — FAQ
How do I blur the background of a photo?
Upload your photo and switch to the Blur mode. The subject is detected and kept sharp while the background is blurred. Use the slider to set how strong the blur is, then download.
Can I control how strong the blur is?
Yes. A slider sets the blur strength, from a subtle softening to a heavy, dreamy background, and the preview updates instantly.
Does the subject stay sharp?
Yes. Only the background is blurred — the cut-out subject is drawn back on top at full sharpness, for a natural portrait look.
Is it free, and where does it run?
It is free with no sign-up, and it runs in your browser on your own device. How any data associated with the tool is handled is described in our privacy policy.
