And if we need a new one anyway, we can take something better like WebP or AVIF-image.
② If you believe that WebP images should be supported in Telegram (in addition to the already supported WebP stickers), consider voting for the WebP-related suggestion at https://bugs.telegram.org/c/1021
③ However, the argument “It can't even be shown with a normal JPEG viewer” is not correct within the scope of this suggestion because a JPEG file can be losslessly transcoded to JPEG XL format (to be stored efficiently, to be delivered faster) and then such JPEG XL can be losslessly transcoded (by a Telegram client) back to JPEG when the user decides to save the image in a JPEG file or to show the image in any JPEG viewer.
④ Hence AVIF and WebP, though also better formats than JPEG (in terms of quality-to size ratio and of compression artifacts' appeal), are worse than JPEG XL within the scope of this suggestion: unlike JPEG XL, they do not offer lossless recompression of JPEG and thus they would incur generation loss (see https://en.wikipedia.org/wiki/Generation_loss for the definition) for every transcoding from JPEG and to JPEG.
Another JXL-related TG issue for general support of the format is here https://bugs.telegram.org/c/15667
