ICO are icon files used by Windows and, often, the web. An ICO file can store one or more images in different sizes, so that they can be appropriately selected based on usage. ICO files can have a size of 256x256 pixels at most.

BMP files, also known as bitmap image files, are uncompressed raster images. They contain a file header with a bitmap identifier, width, height and color settings among other information, as well as bitmap pixels with different colors.
Because of the lack of any compression, BMP files often have a relatively large file size. Therefore, it may be beneficial to convert such images to newer, better-optimized formats like WebP and AVIF.
