The GIF format is a compressed format but without loss of quality. This for a simple reason, it is that it cannot contain more than 256 colors in each layer of the same image, this one supporting the superposition of layers. The GIF also manages transparency which is an advantage for integration into a web page and it is mainly used for animated images. BMP image format is an old image format developed by Microsoft. It can be read by all image programs (viewer or image processing software). The advantage of this format is that it does not degrade image quality. It is indeed not compressed. JPEG format is the most popular format. This is your images taken with your smartphone or digital camera. It is also in this format that you find the majority of images, icons or drawings.
