BMP

The native Windows format (legacy). It stores color information for every pixel without compression, resulting in very large files.

Detailed Analysis

When comparing BMP (Bitmap Image File) with JPG (Joint Photographic Experts Group), it is important to understand the historical and technical context. BMP was established in 1990, while JPG appeared in 1992.

The main technical difference lies in their compression algorithm. BMP uses lossless compression: it keeps all the original data with no quality loss. JPG, on the other hand, uses lossy compression: it discards some data to reduce file size.
