Blur Image Background
Get the portrait-mode look after the fact: AI finds the subject, the background gets a smooth adjustable blur, and the subject stays tack sharp. Processed entirely on your device.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
Portrait mode, applied later
Phone portrait mode blurs the background at capture time — but the best shot is often the one taken without it. Here the same subject/background separation happens after the fact: a segmentation model isolates the person or object, only the background is blurred, and a strength slider takes it from a subtle depth cue to a full creamy bokeh-style blur.
Blur that respects your privacy twice
A blurred background is itself a privacy feature — it hides the messy room, the office whiteboard, the street you live on — and doing it locally means the sharp original never gets uploaded anywhere either. If the automatic mask clips an ear or keeps a stray shoulder, the Restore and Erase brushes fix the boundary before you export as JPG, PNG or WebP.
Frequently asked questions
- Is my photo uploaded to remove the background?
- No. The AI model runs inside your browser using WebAssembly — inference happens on your own device. The only thing ever downloaded is the model itself (once); nothing is ever uploaded.
- Why does the first run download ~55 MB?
- That download is the neural network itself (the ISNet segmentation model plus its runtime). Cloud tools keep the model on their servers — which is exactly why they need your photo. Running it locally means fetching the model once; your browser caches it, so later runs start instantly and even work offline.
- How do I get a transparent background?
- Transparent is the default. After the AI cuts out the subject, download as PNG or WebP — both keep full transparency.
- Can I blur the background instead of removing it?
- Yes. Switch the background to “Blur” and adjust the strength for a portrait-style effect, or pick “Color” for a clean studio look — handy for profile photos and product shots.
- What if the AI misses part of the subject?
- Use the touch-up brushes: Restore paints back anything the AI removed, Erase cleans up leftovers. Edge smoothing softens the cutout line, and you can always reset to the AI result.
- Which photos work best?
- Clear subjects — people, products, animals — on reasonably distinct backgrounds. The “High” model handles tricky details like hair better at the cost of a bigger one-time download.
