Detailed explanation-1: -Uncompressed BMPs can have much larger file sizes than JPEGs and PNGs, making it more difficult to share them. They can also be too big to use on websites or to store on hard drives that don’t have a lot of extra space available.
Detailed explanation-2: -A BMP file contains uncompressed data, making it ideal for storing and displaying high-quality digital images. On the downside, this lack of compression generally creates larger file sizes than, for example, JPEGs and GIFs.
Detailed explanation-3: -The larger the number of pixels in an image, the higher the resolution and file size. The disadvantage of pixel graphics is that scaling the image is associated with a loss of quality. Each pixel has a defined size. If you enlarge a file, the pixels are also stretched and the quality decreases.
