# Create transformation policies
<a name="create-transformation-policies"></a>

Transformation policies define how images are processed based on conditions. You can create policies using either the Admin UI interface or by providing JSON configuration directly.

## Using the Admin UI
<a name="using-the-admin-ui"></a>

1. In the Admin UI, navigate to the **Policies** section.

1. Click **Create Policy** and provide:
   +  **Policy Name**: Descriptive name for the policy
   +  **Description**: Optional description of what the policy does

1. Configure transformations using the UI:
   + Click **Add Transformation** to add image processing operations
   + Select transformation type (resize, format, quality, etc.)
   + Configure transformation parameters using the form fields

1. Configure outputs using the UI:
   + Click **Add Output** to define output specifications
   + Select output type (quality, format, autosize)
   + Configure output parameters using the form fields

1. Click **Save** to create the policy.

## Using Management API

Alternatively, you can create policies by providing JSON configuration directly using the Management API:

1. In the Admin UI, navigate to the **Policies** section.

1. Click **Create Policy** and provide:
   +  **Policy Name**: Descriptive name for the policy
   +  **Description**: Optional description
   +  **Policy JSON**: JSON configuration defining transformations and outputs

1. Example policy JSON:

   ```
