A GIF (Graphics Interchange Format) is a short, silent, looping animation - typically a few seconds long - used to express reactions, humour, or emotion in social media posts, comments, and messages. GIFs are often clipped from films, TV shows, or internet moments, and have become a shorthand for conveying feeling quickly in digital conversation.
Platforms like Twitter/X, Slack, iMessage, and most social comment sections have built-in GIF search tools, making them easy to use without needing to save or upload a file. For brands, GIFs can add personality to responses and posts - though like memes, they work best when used sparingly and contextually rather than as a forced tactic.
