Frequently Asked Questions
Does this blur only the background?
Yes. The tool first detects the foreground subject, blurs the original image and then places the sharp subject over the blurred background.
Can I control the blur strength?
Yes. Use the slider or choose Soft, Portrait, Strong or Max.
Will the face stay sharp?
The tool attempts to keep the detected foreground subject sharp. Results can vary with complex images, hair, transparent objects and multiple subjects.
Does it work on mobile?
Yes. The interface is responsive and works in modern mobile browsers.
Are my images uploaded?
The AI segmentation and image processing run in your browser. The model may be downloaded by the browser on its first use.
Why can the first processing take longer?
The background-removal model has to load the first time. Later processing can be faster because browser caching may keep the model available.
