What is a BMP File?

BMP (Bitmap) is an uncompressed image format developed by Microsoft. It stores color information for each pixel directly, resulting in very large file sizes but no compression-related quality loss. BMP is natively compatible with Windows operating systems and can be used for simple image processing and screen captures. In modern usage, BMP files are generally converted to PNG or JPG formats, which offer much smaller file sizes with comparable quality.
