iterationlayer Smart Crop Avatar and Remove Background
Social platforms and SaaS apps use this recipe to process user-uploaded profile pictures on the fly. Smart crop centers on the face, background removal strips the messy kitchen or parking lot, and WebP conversion keeps file sizes small — ready for consistent, professional-looking avatars.
