What is the difference between .nlm and .png?

Description: The NLM file format, standing for Nokia Logo File, is specifically designed for use with Nokia mobile phones. It contains graphics data used to customize the logo displayed on the phone, such as the startup screen or operator logo. These files allow users to personalize their mobile devices with unique images or designs. The format was more prevalent during the era when Nokia phones dominated the mobile market, supporting a way for users to differentiate their devices.; 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.
