The Pixel editor allows you to complete semantic and panoptic segmentation using edge detection and image segmentation algorithms. The editor includes tools such as Smart segmentation, Brush, and Polygon. The Vector editor allows you complete object detection projects. The editor includes tools such as Points, Polyline, Polygon, Bounding Box, Ellipse, Template, Cuboid, and many more.
To edit a polygon:
  1. Select the polygon.
  2. Select a point.
  3. Drag the point wherever you want.
Select the polygon tool, hold down the left click, and outline your object.
You can add point labels to polylines, polygons, bounding boxes, rotated boxes, ellipses, and cuboids. To add a point label:
  1. Select an instance.
  2. Right-click on a point.
  3. Enter a label name.
  4. Select the check icon.
You can press Tab to shift between different instances.


Your data is in safe hands. Here's how we do it:
  • We use AWS Cognito services and keep your data secure in S3 buckets. Only your team has access to your data.
  • We do not provide any public links. So no one can access your data after you export it.
  • If you request to delete your data, we will delete it the same day.
  • There are seven user roles in SuperAnnotate, and each user role has specific permissions. You can assign a role to each team member, and restrict team members from downloading your data.
  • We sign a mutual NDA when you want to hire annotators through our platform.
There are two main differences between uploading images in the UI and via SDK:
  1. Bulk uploading through the SDK is faster than uploading in the UI.
  2. You can upload up to 2,000 images at a time in the UI, while you can upload up to 50,000 images per folder at a time via SDK.
You can download your annotations in one of the following formats: SuperAnnotate or COCO. You can use converters to convert your annotations from COCO to other formats. Learn more about the SuperAnnotate format.
