GIF

A file format originally created in 1987 for bundling multiple images that evolved into a widely used medium for short, silent, looping animations on the web and social media. GIFs are primarily used in online conversation to express emotions, reactions, and cultural references — functioning as visual shorthand that can convey tone and sentiment more effectively than text alone. In accessibility contexts, GIFs present unique challenges because they are inherently visual yet carry communicative content essential to social participation. Unlike static images, GIFs contain action across multiple frames and often include visual indications of sound, facial expressions, and gestures that are difficult to capture in alternative text alone. Research has found that the vast majority of GIFs on social media lack alt text, effectively excluding people with vision impairments from a significant channel of online communication. Accessible alternatives include descriptive alt text, audio descriptions narrated over source audio, and platform-level solutions that automatically attach descriptions to popular reused GIFs.
