Abstract
Overview
ISO/IEC 18181-2:2026, developed by ISO and IEC, specifies the official file format for the JPEG XL image coding system. As the second part of the JPEG XL series, this international standard defines how JPEG XL codestreams-outlined in -are transported, stored, and organized in files. The document provides comprehensive guidance on structuring JPEG XL files, managing image metadata, and supporting extensibility for various imaging applications. JPEG XL files offer a modern container format supporting metadata, extensions, and efficient image encoding, making them suitable for advanced imaging workflows and digital archiving.
