3D Fax

3D Fax is a computer program, developed for Microsoft Windows by InfoImaging Technologies in the mid-1990s, for file transfer via fax. The program encodes a file into an image, which the user would then print and send via a fax machine or transmit directly from the computer using a fax modem. The recipient would then scan the transmitted image or receive it via a fax modem, and use 3D Fax to decode it back to its original binary form.

InfoImaging claimed a capacity of 40kB per sheet of paper using its image encoding of files,{{cite news |first=Asa |last=Somers |title=Receive a Color Image on a Monochrome Fax Machine |newspaper=PC Mag |date=27 June 1995 |url=https://books.google.com/books?id=kdaEpI3u0qUC&pg=PA61 |page=61}} extended to 110kB (between two fax modems) in the 2.0 version.{{cite news |title=New Products |date=27 November 1995 |newspaper=Computerworld |page=57 |url=https://books.google.com/books?id=DBaA0pFpw9kC&pg=PT66}} InfoWorld's reviewer found that 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.{{cite news |title=3D Fax takes big leap in transferring binary files via fax or modem |date=10 July 1995 |newspaper=InfoWorld |first=Andre |last=Kvitka |page=87 |url=https://books.google.com/books?id=0DoEAAAAMBAJ&pg=PA87}}
