JPEG XL is a plan to develop a compressed image format and/or file format that will be yet another attempt to be the next JPEG. It was first announced around 2017-08.

Identification

Based on draft information, JPEG XL is technically defined as a union of three different top-level formats:

  • General JPEG XL files, which start with bytes ff 0a.
  • Lossless JPEG1 recompressed files, which start with 0a 04 42 d2 d5 4e (see Brunsli).
  • Most standard JPEG files, which start with ff d8 ff e0.
