About BMP to ICO conversion
BMP is introduced by Microsoft in 1987 with Windows 2.0 and is the classic Windows bitmap graphics standard for Windows legacy software, uncompressed pixel data. ICO was created by Microsoft in 1985 and is best for website favicons, Windows desktop icons. Converting BMP to ICO gives you a file that works in the tools and platforms where ICO is required. BMP files can be a problem when their support is limited — converting to ICO solves compatibility issues.
