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.

Prerequisites

You need an Iteration Layer API key. Get one at platform.iterationlayer.com during the 7-day trial.

For full integration guidance (SDKs, auth, MCP, error handling), see the Iteration Layer Integration Guide.
