Given its mediocre compression savings relative to AVIF and its terrible performance relative to WebP, it is hard to imagine a use case for the new format.

As described above, the general meta-box can be used at the file level to contain a description and its associated or included data. This structure is used for MPEG-21 files. A file-level meta-box is used to hold an MPEG-21 Digital Item Declaration (DID) [4], The meta-box also contains a list of attached resources; which may have local names, and may be located within the same file or in another file. The family of the storage file formats is based in the concept of box-structured files. Box structured files are used in a number of applications, and it is possible to form ‘multi-purpose’ files which contain the boxes required by more than one specification. Examples include not only the MPEG-21 file format described here, but also formats using the time-structured part of the ISO Base File Format family. ISO/IEC JTC 1/SC 29/WG 11 (July 2008).

Supported as a format by most standard document editors (like MS Word or Google Docs), and illustration software (AI, Inkscape) but not by image editing software. In theory, the compression is almost twice as efficient as JPEG, leading to images of up to double quality with identical file sizes.

Google Chrome (Version 17+ for desktop, 25+ for mobile), Firefox (65+), Edge (18+), and Opera (11.0+), support WebP natively. Safari’s planned version 14 will support WebP.

MPEG Licensing Authority – MPEG-4 Systems: Introduction". Archived from the original on 2011-01-22 . Retrieved 2011-01-07. MPEG-4 enables different software and hardware developers to create multimedia objects possessing better abilities of adaptability and flexibility to improve the quality of such services and technologies as digital television, animation graphics, the World Wide Web and their extensions. Update 2021-10-22 Jon Sneyers demonstrated it is possible for JPEG-XL to improve upon this PNG by leveraging the advanced group size setting: cjxl poe.png -q 100 -s 9 -g 3 poe.jxl The most common image file types for the web that support transparency are PNG, WebP, GIF, and even SVG. The new format needs support for rich metadata associated to each image in the file. And also support for time metadata for example, for a sequence of images. There is also desire for a new format to be able to include other metadata types for example, audio or text.
