Labelbox documentation


Labelbox supports .png and .jpg image files.

This sample JSON will import two cloud-hosted image files via URL. Use this JSON format when importing via the Labelbox UI or GraphQL API.

        "imageUrl": ""
        "externalId": "2017-Tesla-Model-3-top-view.jpg", 
        "imageUrl": ""


  • externalId is OPTIONAL and is a user-generated file name or ID for the file.

  • imageUrl is REQUIRED and accepts an https:// path to an external image URL.
