Blur Background (Portrait Mode)
Turn any ordinary snapshot into a studio portrait with a soft, blurred background (bokeh effect). Our browser-local AI detects your subject automatically and blurs the background behind them, keeping the person, product or pet razor sharp.
Getting ready…
Your image stays on your device — nothing is uploaded.
Pick a background above, or keep it transparent (checkerboard = see-through). Hold Compare to see the original. Zoom with the buttons or Ctrl + scroll; drag with Space held (or the middle button) to pan.
No phone portrait mode or expensive DSLR lens required. All processing happens locally on your device in your browser; your photos are never uploaded or stored.
Why blur a photo background?
A blurred background directs all attention to the subject while softening messy rooms, busy streets, or distracting clutter. It gives portraits, product headshots, and pet photos a high-end camera aesthetic with natural optical depth of field.
Upload your image, and the tool isolates the foreground and applies a smooth optical lens blur to the background. Download the result as a high-resolution PNG in seconds.

Frequently asked questions
How does the background blur tool work?
The tool uses in-browser machine learning to segment the foreground subject from the background, then applies an optical Gaussian blur to the background layer while preserving edge sharpness on the subject.
Is my photo uploaded to a server to blur it?
No. The AI model runs directly in your browser using WebAssembly. Your photo never leaves your device, keeping personal and family pictures 100% private.
What subjects work best for background blur?
People (headshots, selfies, portraits), pets, products, and cars produce the most striking portrait-mode results.
Can I download the blurred photo in full resolution?
Yes. The final composite downloads at the full original resolution as a high-quality PNG with no watermark.
