The G4 file extension is linked to the CCITT Group 4 Fax Image format, recognized by the International Telecommunication Union (ITU) for its ability to compress monochrome images without data loss. This format is integral to fax technology, employing a two-dimensional coding system that identifies image patterns, resulting in high compression ratios and minimized file sizes, key for efficient document transmission.
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.
