Convert fbm to png

What is the difference between .fbm and .png?

Description: The FBM (Fuzzy Bitmap) file format is a type of image file format that was designed for use with the FrameBufferMan program, which primarily serves the Unix environment. FBM files are used to store bitmap images, which consist of a map of pixels that collectively form an image. This format supports various color depths and can include metadata such as the image's dimensions and color information. The FBM format is specifically tailored for handling graphics with a focus on simplicity and effectiveness in environments where direct and straightforward manipulation of pixel data is required.; 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.
