WBMP (Wireless Bitmap) is a monochrome (1-bit) image format designed for mobile devices in the early days of wireless internet. It was used in WAP (Wireless Application Protocol) pages for simple graphics like icons and buttons. WBMP files are black and white only, with no color or grayscale support, and are now largely obsolete as modern mobile devices support standard image formats.
