About the BMP Format
BMP (Windows Bitmap) is one of the oldest raster image formats, introduced by Microsoft for use in Windows. BMP files store pixel data with little or no compression, resulting in large file sizes but perfect quality retention. The format supports various colour depths from 1-bit monochrome to 32-bit with an alpha channel. BMP is ideal when you need an uncompressed, universally compatible image that can be opened on virtually any system without special software. It is commonly used in Windows applications, embedded systems, and situations where lossless, uncompressed data is essential.
