Setting Image Advanced Compression

Last updated: 2021-04-28 16:00:41


    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.


    • You can use Image Advanced Compression to convert JPG, PNG, GIF, 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 TPG decoder−integrated SDKs 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.
