There are three main factors that determine the size of an image file: pixel dimensions; image format; and colour depth. This refers to the number of pixels in an image: the more pixels that are present, the larger the file size will be.
Q. What can happens if you enlarge a bitmap image?
Explanation: If you enlarge a bitmap image, the image quality will decrease and you can see the individual pixels. This process where the image breaks into individual pixels is called pixelation.

Q. Do bitmap images scale well?
So with bitmaps it is pretty much always OK to make them smaller, because the grid of pixels just gets finer in detail as you scale it down, so it is ideal to start with a larger image and scale it downwards.
Q. When would you use a bitmap image?
Bitmap images are widely used on digital cameras, smartphones and online. Common bitmap image file types include JPEG , GIF and PNG .
Q. What are the pros and cons of bitmap?
BMP: Windows bitmap
| Advantages | Disadvantages |
|---|---|
| An integral part of Windows | Big file outputs even after compression |
| Large colour spectrum | |
| Simply structured |
Q. What are the disadvantages of using bitmap?
One of the disadvantages associated with a bitmap image is that it does not tend to resize very well. While it may be easy to scale down an image without loss of clarity, it is not easy to enlarge the image without the image becoming pixelated. Another disadvantage associated with a bitmap is the large file size.
Q. Is a BMP file high resolution?
BMP or Bitmap Image File is a format developed by Microsoft for Windows. There is no compression or information loss with BMP files which allow images to have very high quality, but also very large file sizes. Due to BMP being a proprietary format, it is generally recommended to use TIFF files.
