EFX to JXR Conversion: FAQ

What are EFX files?

EFX (eFax) is a proprietary file format used by eFax for storing fax documents in digital form. EFX files typically contain fax images, text, and related document data and are commonly created when receiving or saving faxes through eFax services. The format is primarily intended for viewing and managing fax documents within compatible eFax software. Because EFX files are not widely supported by standard image and document applications, conversion to more common formats such as PDF, TIFF, or JPEG can be useful for archiving, sharing, and further processing.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
