libjxl is an open-source library for Windows that implements the JPEG XL image standard. It functions as a reference implementation, offering both encoding and decoding capabilities so developers can add JPEG XL support to their software projects.

Main capabilities

• Provides efficient JPEG XL encoding and decoding engines suitable for programmatic use.
• Includes tools and utilities for working with JPEG XL images from the command line.
• Built to conform with the relevant ISO/IEC specifications for JPEG XL compatibility.

Compatible formats and utilities

• NetPBM
• OpenEXR
• DJXL
• CJXL

Common use cases

• Integrating next-generation image compression into desktop and server applications.
• Image-processing pipelines that need high-quality compression with wide format support.
• Reducing storage and bandwidth for large image collections while preserving visual fidelity.

Integration and deployment notes

libjxl is distributed as a library that other applications can link against, and several programs already incorporate it to add JPEG XL features. Its toolset and format support make it a practical choice when modern image handling and standards compliance are required.
