Compact GIFs for Slack
Slack lets each user control whether animated images play automatically. File size does not override that preference, but trimming to the key moment, using a 320–480px width and choosing 10–15 fps makes the GIF faster to upload and view.

Frequently asked questions
- Why doesn't my GIF move in Slack?
- Slack has a user preference for automatically playing animated images and emoji. Check that setting first; reducing width, length and frame rate still helps the GIF load faster.
