What is a JXR file

JXR is a file extension assigned to a certain kind of raster images. As the full name suggests, JXR is a modified JPEG image. It was developed by Windows to, primarily, be supported by their own media software such as the Windows Photo Viewer. The purpose of the JXR file was to improve the color accuracy of JPG files, as well as supporting better compression.

Files with the JXR extension are mostly used for image and photo editing because the images come in a very high-resolution. They support deep color images (48 bit RGB). Additionally, the JXR image supports both lossy and lossless compression.

Here's a small, but not exhaustive list of programs that can open JXR documents:

  • Adobe Photoshop with plugin (Windows)
  • Axel Rietschin FastPictureViewer (Windows)
  • IrfanView (Windows)
  • Microsoft Windows Photo Viewer (Windows)
  • XnView MP (Windows, Mac & Linux)
