-Description: JPEG XL Image Coding System - "JXL" (command line utility)
- The JPEG XL Image Coding System (ISO/IEC 18181) is a lossy and
- lossless image compression format. It has a rich feature set and is
- particularly optimized for responsive web environments, so that
- content renders well on a wide range of devices. Moreover, it includes
- several features that help transition from the legacy JPEG format.
+Description: Jpegli JPEG codec (command line utility)
+ Jpegli is a new JPEG coding library that is designed to be faster, more
+ efficient, and more visually pleasing than traditional JPEG. It uses a number
+ of new techniques to achieve these goals, including:
+ .
+ 1) It provides both a fully interoperable encoder and decoder complying with
+ the original JPEG standard and its most conventional 8-bit formalism, and
+ API/ABI compatibility with libjpeg-turbo and MozJPEG.
+ .
+ 2) High quality results. When images are compressed or decompressed through
+ Jpegli, more precise and psychovisually effective computations are performed
+ and images will look clearer and have fewer observable artifacts.
+ .
+ 3) Fast. While improving on image quality/compression density ratio, Jpegli's
+ coding speed is comparable to traditional approaches, such as libjpeg-turbo and
+ MozJPEG. This means that web developers can effortlessly integrate Jpegli into
+ their existing workflows without sacrificing coding speed performance or memory
+ use.
+ .
+ 4) 10+ bits. Jpegli can be encoded with 10+ bits per component. Traditional
+ JPEG coding solutions offer only 8 bit per component dynamics causing visible
+ banding artifacts in slow gradients. Jpegli's 10+ bits coding happens in the
+ original 8-bit formalism and the resulting images are fully interoperable with
+ 8-bit viewers. 10+ bit dynamics are available as an API extension and
+ application code changes are needed to benefit from it.
+ .
+ 5) More dense: Jpegli compresses images more efficiently than traditional JPEG
+ codecs, which can save bandwidth and storage space, and speed up web pages.
