FileHint

image/gif

The MIME type for GIF images. Broad animation support keeps it alive for reactions and short clips.

Typical extensions

Primary uses

  • Social reactions and chat stickers
  • Short web animations
  • Lightweight UI motion

In a browser

Every browser plays inline. Animations autoplay; stopping them requires custom UI.

On a server

Use long-lived cache headers. CDNs increasingly transcode GIFs to WebP/AVIF on the fly.

In email

Most clients animate GIFs; older Outlook shows only the first frame.
