Google has released a new JPEG file compression library called Jpegli, which offers a 35% better compression rate compared to the widely used libjpeg62 library. Jpegli has been completely rewritten and employs new techniques for encoding and decoding JPEG files while remaining compatible with the original JPEG standard. Despite improving compression efficiency and reducing file size, Jpegli maintains compression-decompression speed on par with libjpeg-turbo and MozJPG.
One notable feature of Jpegli is its ability to encode colors in 10+ bits, surpassing the current 8-bit encoding limitation of JPEG. This high-bit encoding format remains readable in the traditional JPEG library.
Jpegli is part of the JPEG XL project, aimed at upgrading the original JPEG format, a venture spearheaded by Google and hosted on GitHub as open source code.
TLDR: Google introduces Jpegli, a new JPEG compression library with enhanced compression rates and high-bit color encoding capabilities, as part of the JPEG XL project to upgrade the traditional JPEG format.
