What is a JXL file?

JXL files mostly belong to JPEG XL Viewer.

JXL files are JPEG XL image files that use a next-generation image compression technique.
These files store image data with advanced methods that allow both lossy and lossless compression, reducing file size while maintaining image quality.
Key details compiled by FilExt.com include:

Support for both lossy and lossless compression modes
Utilization of codecs such as the JXL Image Codec and JXL Image Decoder
Enhanced color handling and detail retention over older JPEG methods

FilExt.com note: To open and view a JXL file, use software that supports the JPEG XL format like the JPEG XL Viewer. For more technical details, visit the official JPEG XL webpage.

Programs that open and convert JXL files:

JPEG XL Viewer
See the previous paragraphs to learn more about the main application. JXL files are often referred to as JPEG XL Viewer raster images because this type of file is primarily created or used by this software.
JPEG XL Image Codec
A .jxl file contains an image encoded using the JPEG XL (JXL) image compression codec. JXL is designed to supersede older image formats like JPEG, PNG, and GIF, offering superior compression ratios and features such as lossless compression, high dynamic range (HDR) support, and animation capabilities. The format uses a combination of advanced compression techniques, including wavelet transforms and a novel perceptual model, to achieve smaller file sizes without significant quality loss. Files using the .jxl extension are typically created by image editing software or specialized encoding tools that support the JPEG XL standard. They can be viewed using compatible image viewers or web browsers. The JPEG XL format aims to improve web performance by reducing image file sizes, leading to faster loading times and reduced bandwidth consumption. It also supports progressive decoding, allowing images to be displayed gradually as they download. This file format is classified as Image.
