The mbm file type is associated with the Psion Series 5, a range of personal digital assistants (PDAs) developed in the mid-1990s. MBM files are specifically used to store bitmap images on these devices. These images could be used for various purposes, including as part of applications, for the device's interface, or for user content such as photos or graphics. The format is tailored for the limited processing and display capabilities of PDAs from that era.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
