Frequently Asked Questions

How do I blur only the background?
Upload your image and apply the blur tool. Adjust the blur radius to achieve the desired depth-of-field effect. For selective background blur, use a higher blur value for a more dramatic portrait effect.
What blur radius should I use for backgrounds?
A blur radius of 5-10px creates a subtle, professional look. 15-20px creates a dramatic bokeh effect. Start lower and increase gradually until you achieve the desired background separation.
Can I blur the background on a phone photo?
Yes, upload any phone photo and apply background blur. This works great for selfies and portraits where you want to simulate the depth-of-field effect of a DSLR camera.
