This unit was far easier to operate and could be connected to any standard telephone line. This machine was capable of transmitting a letter-sized document in about six minutes.

3D Fax the 1.0 version could compress both a 90kB Word document and a 302kB image file to less than 40kB, so the files could each be faxed as a single page. 3D Fax 3D Fax was a computer program for file transfer via fax. The program encoded a file into an image to be sent to the recipient's fax machine. The recipient would then scan the transmitted image and use 3D Fax to decode it back to its original binary form. 3D Fax was developed and marketed in the mid-1990s by a company called InfoImaging Technologies; it ran on Windows.
