EFX to GBR 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 GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry. Gerber files include 2-D representations of various PCB images, such as copper layers, solder mask etc. They can also describe the electrical connections on such boards, or drilling and milling info associated with them. Similar formats include GBS, CMP and SOL.
