Frequently Asked Questions

How is this different from Remove Background?

Remove Background gives you a transparent PNG. Blur Background keeps the original background but makes it blurry, creating a natural depth-of-field effect like a DSLR camera.

Can I control how much blur is applied?

Yes! Use the blur slider to adjust from 5px (subtle) to 40px (extreme). The change applies in real-time.

Does it work with multiple subjects?

The AI detects the primary subject(s) in the foreground. Groups of people are generally handled well.

Notes from Milo 🐨

The blur slider used to do nothing after you uploaded — you were stuck with whatever it picked first. Now the AI cutout runs once, then you can slide the blur live and watch the background go soft in real time. Big photos stay smooth too.
