AI-Powered Background Blur for Any Image
Blur Background Generator uses TensorFlow.js-powered AI segmentation to detect people in your image, separate the subject from the background, and apply a customizable blur effect. The subject stays perfectly sharp while the background gets a smooth, professional bokeh-style blur. Everything runs locally in your browser — no uploads, no watermarks, no sign-up.
Smart Subject Detection with Adjustable Blur
The AI model detects subjects in your image, creates a precise segmentation mask with edge erosion and feathering for natural transitions, then separates foreground from background before applying blur — eliminating halos and color bleeding.
Adjust the blur intensity from 0 to 50px with the slider and see the result update in real-time. All processing happens client-side in your browser, so your images never leave your device.
