Cloud Infinite provides the advanced image compression feature, which can convert images into highly efficient formats such as AVIF, HEIF, or TPG. This effectively reduces latency in image transmission and loading time, while lowering bandwidth and traffic costs.
Function
Introduction
AVIF compression
It can convert images to the AVIF format. AVIF is a new image format based on AV1, first made public by Netflix in February 2020. It is currently supported by browsers such as Chrome and Firefox. Native support for AVIF is now available on iOS 16 or later and Android 12 or later systems.
HEIF compression
Images can be converted to the HEIF format, which features ultra-high compression rates. At the same image quality, it reduces image size by over 80% compared to JPG. iOS has adopted HEIF as the default format for albums, and Android P natively supports HEIF.
TPG compression
TPG is a self-developed image format introduced by Tencent. It can convert images in formats such as JPG, PNG, and WebP to TPG format, significantly reducing image size.
ASTC compression
ASTC is a texture compression format specifically designed for GPU rendering, suitable for graphics rendering scenarios on mobile devices such as mobile gaming and 3D graphics.
The advanced image compression feature meets multi-terminal image compression requirements for PC, App, and so on. It is suitable for business scenarios such as e-commerce and media, effectively reducing latency in image transmission and loading time, and lowering bandwidth and traffic costs.
Different compression features have varying compatibility with existing image formats, browser environments, and so on. Refer to the table below for details.
