Description: XHTML files are a type of markup language document used to create webpages. It is an XML-based version of HTML and is designed to meet the needs of Web developers. XHTML files have a .xhtml extension and can be viewed in any web browser.; A JPEG XL file is an image saved in a compressed graphic format currently under development by the Joint Photographic Experts Group (JPEG). It supports wide color gamut and HDR (High Dynamic Range), alpha channels and animation frames while providing visually lossless compression. Images can be converted back and forth between JPEG XL and JPEG without loss of quality. Converting a regular JPEG to JPEG XL reduces the file size by 22%. JPEG XL files can be used to store any type of image content.
