The BMP (Bitmap) image format is a straightforward and uncompressed raster image format, storing pixel data without any loss of quality. BMP files are known for their simplicity and support for various color depths, including monochrome, grayscale, and full-color images. However, due to the lack of compression, BMP files tend to be larger in size compared to other image formats, making them less commonly used in scenarios where file size efficiency is crucial. The .bmp file extension is associated with BMP files, which are often used in applications that require high-quality, uncompressed image storage.
