What is Blur Background?
Blur Background keeps people and products sharp while softening everything behind them. Subject masking runs in your browser with U²-Net-P — your photo is not uploaded for AI cutout. Adjust blur strength, refine hair edges with erase/restore, then download at original resolution. This is subject-masked background blur, not depth-estimated DSLR bokeh.
Key features
- Browser-local subject mask — no photo upload for AI
- Adjustable blur strength; subject stays sharp
- Erase / restore brush and edge cleanup for hair
- Before/after compare; full-resolution PNG, JPG or WebP
- Honest: not depth-map / lens bokeh unless stated elsewhere
Popular uses
- Portrait-style look for phone photos
- Hide a busy room behind a profile or product shot
- Make the subject stand out in thumbnails
Supported formats
Input: JPG, PNG, WebP, AVIF, HEIC/HEIF, GIF, BMP, TIFF. Output: PNG, JPG or WebP.
Troubleshooting
- Hair or edges look cut Use the restore brush along the edge, enable Clean edge colours, or lower blur for a softer transition.
- On-device AI failed Try Chrome/Edge, or refine a plain-background Auto cut with erase/restore. Photos are not sent to the server.
Also known as: Blur Photo Background, Portrait Blur, Subject Background Blur, Background Blur Editor.
How it works
- Open a photo. On-device U²-Net-P finds the subject; Auto blurs only the background.
- Adjust blur strength; refine hair and edges with erase/restore if needed.
- Download PNG, JPG or WebP at the same resolution. For a new colour/image background, use Change Background.
FAQ
Is my photo uploaded?
No — subject masking runs in your browser. Blur and download stay on this device.
Is this real DSLR bokeh / depth blur?
No. It is subject-masked background blur (sharp subject, softened background), not a depth map or camera lens simulation.
Does it lower the resolution?
No. The result is rendered from your original photo at the same width and height.
Is this real DSLR bokeh?
No. It softens the background behind a subject mask. It does not estimate a depth map or simulate a camera lens.
