JPEG XL is a work-in-progress compressed image format and/or file format that is yet another attempt to be the next JPEG. It was first announced around 2017-08. It is expected to be released as ISO/IEC 18181.
Identification
Based on draft information, JPEG XL is technically defined as a union of three different top-level formats:
- Normal 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.
