What is MKV?
MKV (Matroska) is an open, royalty-free container that can hold any number of video, audio and subtitle tracks plus chapters in a single file. It is popular for films and archives, but many phones, TVs and editors do not open it natively.
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 MKV to GIF
- GIFs have no sound and at most 256 colours, so the GIF will look flatter than the MKV 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.
