      Overview

      Image Processing is a set of image processing capabilities provided by Cloud Infinite (CI). It supports basic processing capabilities such as image cropping, format conversion, scaling, and watermarking, image downsizing capabilities such as Guetzli compression and AVIF transcoding and compression, blind watermarking for copyright protection, and AI-based recognition and analysis features such as image enhancement, tagging, scoring, and repair and image matting, meeting your image processing requirements in diverse business scenarios.
      Note:
      Image Processing is available only in public cloud regions.
      Image Processing is charged by CI. For detailed pricing, see Basic image processing fee in Billing and Pricing.
      Currently, image processing is not supported for multi-AZ buckets.
