GIF (Graphics Interchange Format) is a digital image format that uses multiple frames of an image or video without sound to create a short, repetitive animation. This repetitive property distinguishes GIFs from other image files such as JPEGs or PNGs.
GIFs are often used as a form of self-expression on social media and in communication applications to convey emotions, reactions, and humor. Many GIFs, such as Nyan Cat, have become pop culture icons.
In web design, GIFs can add visual interest, demonstrate how a product works, or provide instruction. However, their larger file size can increase the loading time of web pages and should therefore be used sparingly.
