What is AVI?
AVI is one of the oldest video containers, introduced by Microsoft for Windows. It is simple and still opens on older players and DVD hardware, but it lacks modern features such as efficient streaming and reliable subtitle support, and files tend to be large.
What is GIF?
GIF is the classic format for short animations and memes. It plays automatically and loops in every browser and chat app, but it is limited to 256 colours per frame and stores video very inefficiently, so animated GIFs are often many times larger than the same clip as MP4.
Tips for converting AVI to GIF
- GIFs have no sound and at most 256 colours, so the GIF will look flatter than the AVI and play silently.
- Keep clips short: a few seconds of GIF can weigh more than a minute of video.
- If the clip is for a website or a chat app, an MP4 or WebM usually looks better and loads faster than a GIF.
- Keep the original video; converting to GIF is not reversible without loss.
