They have a large file size because information has to be stored about every pixel

Detailed explanation-1: -However, bitmap images are not as well-suited to creating scalable graphics as vector images are. Because they are resolution-dependent, they can become pixelated or blurry when they are scaled up, which makes them less suitable for creating logos or other graphics that need to be resized.
Detailed explanation-2: -The disadvantage is that compression of an image file leads to the loss of image data due to the combination of similar pixels, which in turn leads to a loss of quality. This is also the main difference between JPG files and the PNG format.
Detailed explanation-3: -The Raster (Bitmap) image becomes blurry when enlarged, however the Vector image keeps the same resolution regardless of enlarging the size.
Detailed explanation-4: -Bitmap files, however, do have drawbacks: They can be very large, particularly if the image contains a large number of colors. Data compression can shrink the size of pixel data, but the data must be expanded before it can be used, and this can slow down the reading and rendering process considerably.
