What is Background Blur?

Background Blur is a free online tool that uses AI to automatically detect and blur the background of photos. You upload an image, and the tool applies blur effects to everything behind your subject, making the foreground stand out without manual editing. It's designed for anyone who wants to improve photo composition quickly, whether you're preparing images for professional use, social media, or just tidying up casual photos. The tool handles the technical work of distinguishing subject from background, so you don't need photo editing skills or software.
