EFX to U3D 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 U3D files?

U3D (Universal 3D) is a standardized file format used to store and exchange 3D models and scenes. It supports geometry, textures, colors, lighting, and animations, allowing complex 3D content to be represented efficiently.

The format is widely used in engineering, architecture, manufacturing, medical imaging, and scientific visualization.
