The JPEG Extended Range (JXR) is a still-image compression standard and file format developed by Microsoft, named initially HD Photo. The JXR format is designed to compress continuous-tone photographic images efficiently. The format supports both lossy and lossless types of compression, making it a preferred image format for specific applications such as Ecma-388 Open XML Paper Specification documents.
The JXR, with file extensions .jxr, .hdp, and .wdp, is a JPEG-encoded image file containing graphics, chroma, and metadata that can be compressed using lossless or lossy techniques. The structure of a JXR file is similar to a TIFF-like format that uses a table of Image File Directory (IFD) tags to store image data, metadata, optional alpha channel data, optional Exif metadata, and optional XMP metadata stored as RDF/XML.
The JXR format offers improved color accuracy and supports lossless compression compared to the standard JPEG format. The ability to store high-resolution images without perceivable loss in quality makes JXR advantageous for editing and storing high-resolution images.
