Over The Air Bitmap Image (.otb)

The OTB (Over The Air Bitmap) file extension, developed by Nokia, is used for transmitting black and white bitmap images between mobile phones, particularly Nokia and Siemens models. These images, with a maximum resolution of 255x255 pixels, are often sent via SMS in either hexadecimal text or binary format. Historically, OTB files were popular in the early days of mobile communication for sending simple graphics, icons, and wallpapers when data transmission speeds were limited.

Facsimile Image (.fax)

The FAX file extension, short for "facsimile", is primarily associated with digital fax documents. These files are typically saved in TIFF format and are used to store images of documents sent or received via fax software. Historically, fax technology allowed the transmission of scanned printed material over telephone networks, a practice that became widespread in the 1980s and 1990s. Today, FAX files facilitate the digital handling of these documents, enabling easy archiving and viewing with compatible image viewers.
