What is the difference between jpg gif and other formats?

Different image compression formats, in short, the image quality of jpg is better than gif, but gif images are generally smaller than jpg, as follows:

GIF is a graphic interchange format, which has the following characteristics:

(1)GIF only supports pictures with less than 256 colors;

(2)GIF is stored in lossless compression mode, which can generate very small files without affecting the image quality;

(3) Support transparent color, which can make the image emerge on the background;

(4)GIF files can be animated, which is its most prominent feature.

Many characteristics of GIF file just meet the needs of the Internet, so it has become the most popular image format on the Internet, and its appearance has injected a fresh vitality into the Internet. GIF files are also different from other files.

First, we should make each single frame of GIF animation in the image processing software, then connect these still pictures together with the software specially making GIF files, then determine the time interval between frames, and finally save them in GIF format.

There are many softwares for making GIF files, such as Animagic GIF, GIF construction set, GIF movie gear, Ulead Gif Animator and so on.

JPEG image format: JPG extension, full name is Joint Photographic Experts Group. JPEG is a file compression format that can provide excellent image quality. The photos taken in JPEG format have been processed by the image processor inside the camera and can be released directly. Moreover, in most digital cameras, this "processing" function is excellent, and I can say responsibly that JPEG is a trustworthy storage format. Although JPEG is a lossy compression format, generally speaking, as long as you don't pursue too fine image quality (it is difficult for ordinary consumer-grade DC to pursue images), you will find that JPEG has many advantages worth considering. The so-called compression format is that JPEG obtains an image data and reduces its storage size by removing redundant data, but some data of the original image lost in the compression process cannot be recovered. Generally, the compression ratio is between 10: 1 and 40: 1, so JPEG can save a large part of memory card space, thus greatly increasing the number of pictures taken and speeding up the storage speed of photos, which also speeds up the speed of continuous shooting, so it is widely used in news photography. With so many benefits, JPEG files with low compression ratio (high quality) are a good choice for most people and ordinary families.
