AI Background Blur FAQs

How does the AI background blur tool work?
Our tool uses a state-of-the-art neural network to identify the main subject (foreground) in your image and create an accurate depth map. It then applies a high-quality Gaussian lens blur to the background layer while keeping the subject perfectly sharp.
Can I adjust the blur strength?
Yes! You can choose between different preset levels or use the slider controls to find the exact blur amount that looks best for your portrait.
Does it support high-resolution photo uploads?
Yes, absolutely. The tool processes and exports your photos in their original upload resolutions so that you don't lose any detail or picture quality.
