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.
The JNG format expertly blends JPEG's compression with PNG's transparency. Developed by the PNG Development Group, it's a member of the MNG family, designed for embedding lossy JPEG images in animations. While JNG files are more compact, they may exhibit typical JPEG compression artifacts.
