The AI Background Blur Tool is a free web-based application that uses MediaPipe AI to automatically separate subjects from backgrounds and apply professional-quality blur effects entirely in the browser.
What is the AI Background Blur Tool?
The AI Background Blur Tool is a free online tool that blurs the background of portrait and product photos while keeping the subject sharp. It takes an image (JPG, JPEG, or PNG) as input and outputs a blurred background image with adjustable blur intensity. Processing happens locally in the user's browser—no images are uploaded to any server. The tool is developed and maintained by BB Image Tools (blurbg.com).
