Wireless Bitmap (.wbmp)
The WBMP file extension, which refers to Wireless Bitmap, created by the WAP Forum, is a monochrome graphics format for mobile devices. It supports 1-bit image data, ensuring minimal file sizes and efficient wireless transmission. Initially popular for sending images via SMS, its simple structure was ideal for devices with limited processing power. However, as technology advanced, WBMP was replaced by more complex formats, making it largely obsolete today.
