Mozilla has finally officially responded to the question of whether or not it supports the JPEG-XL format, and has expressed a “neutral” attitude. Mozilla has finally made it official and said it is “neutral” on the support of JPEG-XL format.
Google announced in December last year that it would remove support for the JPEG-XL image format from its Chrome / Chromium web browsers.
Google engineers believe that there is not enough interest in JPEG-XL and that the format does not have enough advantages over existing image formats. Google plans to remove support for JPEG-XL in Chrome 110, and action is already underway.
Mozilla is not yet clear whether it will follow Google’s actions, but officially said that it will be “neutral” attitude.
"We asked a lot of users and experts (sorry for the delay) and the final conclusion is that we are neutral on JPEG-XL. One thing that has to be admitted is that both sides gave relatively good reasons. There is a cost to adding new image formats, both for us (adding, protecting and maintaining code is important) and for the Internet as a whole. In general, fewer formats benefit the Web by reducing the complexity of creating and delivering content. We will provide as many formats as possible to the extent that they meet the needs of users and developers. We evaluate formats based on a combination of the features they provide, overall performance, and a host of other factors, including compression, CPU cost, and image quality. We can also look at the range of uses for a format; for widely used formats, feature and performance advantages are not important. New formats need to justify their rollout and offer some advantages that existing formats cannot."
