iterationlayer Smart Crop Group Photo
HR platforms and event organizers extract individual headshots from team or group photos using AI-powered face detection to crop around the most prominent subject. Upload a group photo, apply smart crop to center on the detected face, and convert to JPEG — ready for employee directories, badges, or social profiles.
