What blur radius creates a realistic bokeh effect?

A radius of 5-10 produces a subtle, natural-looking background blur. Higher values (15-30) create a more dramatic, dreamy effect.

Can I blur the background of a smartphone photo?

Yes. This tool works with any image regardless of the camera used. It is especially useful for phones that lack portrait mode.

Does this auto-detect the background?

Currently you manually select the background regions to blur, giving you precise control over which areas are affected.
