What is JPEG XL?

JPEG XL is a next-generation image compression codec designed to improve upon the limitations of its predecessors, such as JPEG and PNG. It offers superior image quality at lower file sizes, supporting both lossy and lossless compression. This means users can choose between maximizing image quality while minimizing file size or preserving the image data perfectly without any loss. It’s widely seen as a potential successor to JPEG and PNG, though adoption is still growing. Examples of its use include online image galleries, websites, and digital printing, where high-quality images with smaller file sizes are crucial.

Q&A

How does JPEG XL compare to JPEG?

JPEG XL generally produces superior image quality at lower file sizes compared to JPEG, particularly in areas with sharp details and gradients. JPEG XL also supports lossless compression which JPEG does not.

Is JPEG XL widely supported yet?

Support for JPEG XL is growing but not yet universal. While many modern browsers and image editing software are adding support, older systems might not be compatible.
