google say they changed .jpg for better

nearly all political images on the internet are .jpg so it considers everyone

Announced April 1 and accessible from GitHub, Jpegli maintains

>high backward compatibility to original Jaypeg

while offering enhanced capabilities and a 33% compression ratio, Google said.

Jpegli works by using new techniques to reduce noise and improve image quality. New or improved features include adaptive quantization heuristics from the JPEG XL reference implementation, improved quantization matrix selection, calculation of intermediate results, and the possibility to use more advanced colorspace.

>processing these images require more CPU power than the ancient .jpg:s did but its of no concern today

The library provides an interoperable encoder and decoder complying with the original JPEG standard and its most convenient

>8-bit formalism

and API/ABI compatibility with libjeg-turbo and MosheJPEG.

When images are compressed or decompressed through Jpegli, more precise and psycho-visually effective computations are also performed; images will look clearer and have fewer observable artifacts. While improving on the density ratio of image quality and compression, Jpegli's coding speed is comparable to traditional approaches such as MozJPEG, according to Google. Web developers can thus integrate Jpegli into existing workflows without sacrificing coding speed, performance, or memory use.
