About this tool
Our free blur-background tool gives any photo a clean, professional depth-of-field look by keeping the subject sharp and gently blurring everything behind them. It's perfect for profile pictures and headshots, product photos that need a distraction-free backdrop, and portraits where a busy background pulls attention away from the person. An AI model detects the subject automatically — no manual masking — and a strength slider lets you choose anything from a subtle softening to a strong, dramatic blur. Unlike many free editors, there's no signup, no limit and no watermark, and because the AI runs entirely in your browser, your photo is never uploaded to a server. If you'd rather remove the background completely, try our Background Remover. Works in Chrome, Firefox, Safari and Edge on desktop and mobile.
