Phones shoot everything equally sharp, so the passers-by, signs and trash cans behind you are in focus too. Portrait mode doesn't always help, and editor blur tools tend to chew up hair and clothing edges. AI understands what matters in the shot and blurs the background with depth in mind — nearby objects a little softer, distant ones much more, like a real lens at a wide aperture.
Open the AI Photo Editor, upload a photo and write: "blur the background like a portrait lens, keep the person sharp". GPT Image 2.5 is the model to use here — it produces strong, natural-looking bokeh and works carefully around hair, hands and fine details. Control the strength in words: "slightly blur" or "heavily blur the street and the people".
Background blur works for portraits, pets, products and food. Your original stays untouched and every version is saved separately. If you'd rather replace the background or remove it entirely, use Change Background or Remove Background.
