Convert bmx to png

What is the difference between .bmx and .png?

Description: The BMX file format is associated with Siemens Mobile phones, particularly used for storing bitmap graphics on these devices. It is a proprietary image format developed by Siemens for their range of mobile phones, enabling the storage and display of pictures, such as wallpapers or caller ID photos. The format is optimized for the limited storage and display capabilities of early mobile devices. To view or edit BMX files on a computer, specialized software or converters are often required to translate the format into more commonly used image standards.; 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.
