Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
How does the AI Background Blur work locally?
We run an in-browser WebAssembly segmentation engine to separate your subject from the background, and then apply canvas blur layers natively.
Can I change the blur intensity and style?
Yes, you can adjust the blur size, edge feathering, and choose between Gaussian, Zoom/Radial, or Motion blur styles in real-time.
How do I blur the background of a photo for free online?
With KuberAgent Background Blur tool, simply upload your image and the AI segmentation engine automatically detects the subject and blurs everything behind it — no manual selection or software download needed.
Does this background blur tool work without uploading my photo to a server?
Yes. KuberAgent processes the AI segmentation entirely inside your browser using WebAssembly, so your photo is processed locally and never leaves your device or gets uploaded anywhere.
Can I blur the background of a photo like a portrait or DSLR shot (bokeh effect)?
Yes, the tool can replicate a bokeh-style background blur similar to a DSLR camera, with adjustable blur intensity to control how strong or soft the effect looks.
What's the difference between Gaussian, Zoom, and Motion blur styles?
Gaussian blur gives a smooth, even softness across the background — ideal for portraits. Zoom/Radial blur creates a sense of motion pulling outward from the subject. Motion blur simulates directional camera movement, often used for dynamic or sports-style photos.
Will the AI accurately detect edges like hair or fur in the photo?
Edge feathering is built in specifically to handle fine details like hair strands and fur, blending the subject's boundary smoothly into the blurred background instead of leaving a hard, cut-out edge.
Can I remove the background from a photo without using Photoshop?
Yes — kuberagent.com gives you a Photoshop-quality background removal experience without needing any design software or technical skills. Just upload and download.
What image formats can I use for background blur?
The tool accepts common formats including JPEG, PNG, and WebP, and lets you download the final blurred image in the same or PNG format.
