EFX to MIF 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 MIF files?

The MIF extension can be associated with vector images under the MapInfo Interchange Format, in which case it consists of a map and a database exporting file. Also MIF or MIFF file format represents a raster image associated with ImageMagick. This open source program is specialized in editing images, and it is mostly popular among developers as it doesn't have an advanced graphical user interface, so it can mainly be used under command-line. reaConverter supports both types of MIF formats and can convert to vector MIF if the source file is also a vector, and to raster if the source file is a raster image.
