EFX to QRT 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 QRT files?

The QRT format file is associated with the QRT Ray Tracer, also referred to as Quick Ray Tracer. QRTs are uncompressed raster graphic images which contain 3D scenes for ray tracing. Although they haven't been used very frequently in past years, they can be used for various rendering applications.
