Manual Background Blur

Paint over the background with the blur brush to create a depth-of-field effect. Unlike AI-based tools, you have full control over exactly which areas get blurred. Adjust brush size and blur intensity.

Frequently Asked Questions

How do I blur just the background?

Paint over the areas you want to blur using the brush. The unpainted areas (your subject) stay sharp.

Can I adjust the blur after painting?

Yes — change the blur strength slider and click Apply. The mask you painted is preserved.

Is it as good as AI background blur?

It gives you full manual control, which can be more precise than AI for complex scenes. Paint exactly where you want the blur.
