Overview

COS’s CI-based Image Advanced Compression allows you to easily convert images into formats that provide a high compression ratio, such as TPG and HEIF. This effectively reduces the transmission time, loading time, and the use of bandwidth and traffic.

Note：

• You can use Image Advanced Compression to convert JPG, PNG, or WebP images into TPG or HEIF.
• To use the TPG format, ensure that the environment where images are loaded supports TPG decoding. CI provides the TPG decoder−integrated SDK for iOS, Android, and Windows clients to facilitate quick integration with TPG.
• Currently, iOS 11 or later and Android P have native support for the HEIF format.
• Image Advanced Compression is charged by CI. For detailed pricing, please see Billing and Pricing.
