Convert mbm to png

What is the difference between .mbm and .png?

Description: 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 PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
