JPEG XL is a 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 published as ISO/IEC 18181.
JPEG XL is based in part on the FUIF and PIK formats.[1] The standard also supports recompression of JPEG files with bit-exact reconstruction.

Identification
Based on the reference implementation, JPEG XL codestreams start with bytes ff 0a.
Codestreams may also be wrapped in an ISOBMFF-based file format (implementation). See format overview.
