4K What Is an AI Tool for Blurred Background Photos?
AI Background Blur simulates a shallow depth-of-field effect by keeping the main subject sharp and blurring only the background. On KOOX AI, it now defaults to 4K output, making it more suitable for portraits, product images, social creatives, and other detail-sensitive visuals.
How to Create 4K AI Background Blur for Photos
Upload your image and let KOOX AI generate a default 4K blurred-background result while keeping the subject crisp, natural, and ready for portrait, product, or social use.
