The RLE (Run-Length Encoded) file extension, associated with the Utah Raster Toolkit, is a lossless image compression format used primarily for 4 or 8-bit bitmap images. Developed at the University of Utah, it employs run-length encoding to compress data by reducing consecutive repeated values, making it efficient for simple graphics like icons and line drawings. Historically, it was widely used in early versions of Windows and CompuServe software.
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.
