image extension

Windows 11 users can enhance image handling with the JPEG XL image extension, available for download from the Microsoft Store. This feature requires Windows 11 version 24H2 and allows users to view and save images in the .jxl format. The extension also enables conversion of existing JPEG files to the lossless JPEG XL format, reducing file sizes while preserving image quality, and allows reverting JPEG XL files back to the original JPEG format. JPEG XL offers advantages over traditional JPEG, including improved compression efficiency, support for a broad color scale (32 bits), high bit depth, dynamic range, animation, alpha channels, layers, thumbnails, and both lossless and progressive coding. It is designed for optimal display across various devices and is suitable for web content and professional photography. The codec is efficient for computational processing without needing additional hardware acceleration, benefiting mobile devices.
