What is the difference between .otb and .wbmp?

Description: The OTB (Nokia Over The Air Bitmap Image) file format is a type of image file developed for use on Nokia mobile devices. These files are specifically optimized for efficient transmission and display on Nokia phones, particularly older models. The OTB format is designed to be compact to facilitate over-the-air (OTA) transmission, which was an essential feature in the era of limited bandwidth and data transfer capabilities. The format supports monochrome graphics, making it suitable for simple images like icons and logos.; The WBMP (Wireless Bitmap Image) file format is a monochrome graphics format optimized for mobile computing devices with limited display capabilities. It was developed for use in the early days of mobile internet to display images on mobile phones and other wireless devices with minimal processing power and storage. WBMP files contain bitmap images that are typically small and use a black and white color palette, making them highly efficient for fast loading times and minimal data usage.
