Image Advanced Compression

Last updated: 2024-01-31 16:44:15


    CI’s 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.
    TPG compression
    TPG is a Tencent-designed image format. Converting JPG, PNG, or WebP images into TPG greatly reduces the image sizes.
    HEIF compression
    If your images are used in iOS environments, you can convert them from JPG, PNG, GIF, WebP, or other formats into HEIF, which offers an ultra-high compression ratio.
    To use the TPG format, ensure that the environment where images are loaded supports TPG decoding. Tencent Cloud’s multimedia laboratory 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.
