Convert MKV to GIF
Convert MKV to GIF for free, right here in your browser. The video never leaves your device, however large it is.
- Free
- Runs on your device
- No account
- No limits
One file at a time. The video is converted on your own device, so nothing is uploaded and there's no size limit beyond what your browser can hold.
How to convert MKV to GIF
- Drop your MKV file in the box above, or click the box to pick one.
- The first video also fetches the conversion engine, about 7MB, which your browser then keeps. After that it starts straight away.
- Watch the progress bar. Your own machine is doing the work, so leave the tab open until it finishes, then download.
Why convert MKV to GIF?
Turns a few seconds of MKV into something that plays by itself anywhere a picture does.
A GIF has to be built frame by frame, so this takes a few seconds rather than being instant. Keep the clip short, because a GIF is far larger than the video it came from.
Expect the GIF to be bigger than the video, often several times bigger, because a GIF cannot compress motion the way a video codec does. Trimming to the seconds that matter helps more than anything else.
About the two formats
MKV: The container that holds anything. Popular for films and archives, less welcome on phones and websites.
GIF: Silent, short and it plays anywhere a picture does. Enormous files for what you get, so keep it brief.
A video file is a box with codecs inside it, and the box and its contents are separate things. Moving a video into a different box is bookkeeping, and takes a second. Changing the codec means rebuilding every frame, and takes about as long as the video runs. That's the whole difference between the quick conversions here and the slow ones.
Common questions
Is the MKV to GIF converter free?
Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.
Are my files uploaded to a server?
No. The MKV to GIF converter runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.
How do I turn a MKV into a GIF?
Drop the file and it's converted at a size and frame rate chosen to keep the result usable, since a GIF at full resolution and 30 frames a second would be enormous. A palette is built from your own footage rather than using the standard web colours, which is the difference between a GIF that looks like the video and one that looks like 1998.
Why is my GIF so much bigger than the video?
Because GIF has no idea how to compress motion. A video codec stores what changed between frames, while a GIF stores whole pictures over and over. That's why a ten second clip can turn into several megabytes, and why keeping it to the few seconds that matter is the single most useful thing you can do.
Is there a limit on the size of the video?
Not one we set, but there's a practical one. The whole file is held in your browser's memory while it works, so very large files can run a tab out of room, and a phone gives up sooner than a computer. Files up to a few hundred megabytes are comfortable on an ordinary machine.
