GIF is one of the most common raster image formats. Its name is an abbreviation for Graphics Interchange Format File. The developer is the CompuServe organization. A feature of this particular image format is its ability to support the animation function. You can edit animated GIFs in different programs (for example, Easy GIF Animator). Animation is achieved due to the fact that a file of this format carries in itself in a certain sequence several raster images at once. With a depth of up to 256 colors, significant data compression in GIF files is possible without loss of quality.
SVG is one of the formats of two-dimensional vector graphic files that are created on the basis of documents in XML format. The developer is Adobe Systems, and the name of the format is an abbreviation for Scalable Vector Graphics File. In the SVG format, not only two-dimensional vector images can be created, but also mixed vector-raster images. At the same time, SVG files are text files, and therefore they can be opened in most popular text editors. This extension is able to support both static and animated graphics. At the same time, when working with such files, editing occurs without loss of quality.
