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.

Joint Bi-level Image Group (.jbig)

The JBIG (Joint Bi-level Image Group) file extension, standardized as ISO/IEC 11544 and ITU-T T.82 in 1993, is a lossless image compression format primarily used for binary images, such as those in fax transmissions. Developed by the Joint Bi-level Image Experts Group, JBIG offers significant compression efficiency over previous standards, achieving up to 50% better compression than Fax Group 4. Its history dates back to 1988 when ISO and CCITT collaborated to create a unified standard for bi-level image coding.
