--- Comment #120 from Mehmet gelisin <mehmetgelisin at aol.com> ---
Erik Andre from the Images Infra team at Facebook here. http://www-look-4.com/  I'd like to share a bit of our view on JPEG XL in the context of new image formats (e.g AVIF, JPEG XL, WEBP2, ...) http://www.compilatori.com/  and how browser adoption will let us move forward with our plans to test and hopefully roll out JPEG XL. http://www.wearelondonmade.com/ 

After spending the last 5 months investigating and evaluating http://www.jopspeech.com/  JPEG XL from both a performance and quality point of view, it's our opinion that JPEG XL has the most potential of the new  http://joerg.li/ generation of image formats that are trying to succeed JPEG.
This opinion is based on the following findings: http://connstr.net/ 

* JPEG XL encoding at speed/effort 6 is as fast as JPEG encoding (using MozJpeg with Trellis encoding enabled). http://embermanchester.uk/  This means that it's practical to encode JPEG XL images on the fly and serve to client. This can be http://www.slipstone.co.uk/ compared with the encoding speed of AVIF which necessitates offline encoding which offers less flexibility when it comes to delivering http://www.logoarts.co.uk/  dynamically sized and compressed content.
* Depending on the settings used, JPEG XL can also be very fast to decode. http://www.acpirateradio.co.uk/ Our mobile benchmarks show that we can reach parity with JPEG when using multiple threads to decode. This matches and in many cases surpasses the decoding performance https://waytowhatsnext.com/ of other new image formats.
* The JPEG XL image format offers flexible support for progressive decoding, allowing quick preview to be rendered based on just the DC components, or multiple intermediate images without being limited to a fixed set of scans chosen at encode time (i.e progressive JPEG scans). https://www.webb-dev.co.uk/

Having browser support from all the major browsers is going to make our lives a lot easier in upcoming WWW experiments and ensure that we can deliver a consistent experience across platforms and browsers. http://www.iu-bloomington.com/
