Upload the MKV file and our converter samples frames (default 15 fps), encodes them into an animated GIF container, and applies palette quantization tuned for the GIF format (GIF GIF uses an adaptive 256-color palette; animated WebP supports full 24-bit color).
How short / long should my MKV be for a good GIF?
+
Animated GIF is best for clips under 10 seconds. Longer than that and the file balloons (animated GIF is uncompressed-per-frame); use GIF WebP or APNG for longer animations, both of which compress similarly to video codecs.
What is the file size of a 5-second GIF animation from a MKV clip?
Yes — animated GIF GIF is universally supported. Animated WebP plays on Twitter, Discord and modern browsers but not on iMessage or older Slack clients. If maximum compatibility matters, target GIF; if file size matters, target WebP.
