Blur portrait background with AI
Runs entirely on your device. The first run downloads a one-time ~45 MB AI model (cached afterward).
Apply a professional bokeh blur effect to the background of any photo while keeping the subject sharp. Ideal for portrait shots, product photography, and headshots where you want depth-of-field without a DSLR — all processed locally in your browser.
How to Use
Select any JPG, PNG, or WebP photo with a person or main subject.
The neural network keeps the subject tack-sharp while creating a depth mask for the background.
Fine-tune the blur slider from subtle softness to creamy f/1.4 lens bokeh.
Export the finished high-resolution photo with smooth background blur.
Our AI segmentation model computes a smooth edge feathering gradient around hair strands and clothing borders, applying optical Gaussian depth blur exclusively to the background layer without spilling over your subject.
Yes! Use the blur slider to adjust blur strength from subtle lens depth-of-field to strong DSLR portrait bokeh.
Photos with a distinct main subject or clear person portrait work best. For group photos, adjust subject isolation sensitivity for best results.
