What happens to your file
MKV files are common for archiving movies, OBS recordings, multi-language video, but not every app or device opens them. GIF is the better choice for reactions, memes, short loops in chats, emails and docs. Spool converts MKV to GIF with FFmpeg — real decoding and encoding, not a renamed file extension.
Built for quality GIFs. We scale with the Lanczos filter, generate a palette optimized for your exact clip and dither it, which produces richer color and fewer artifacts than single-pass converters. Choose the start time, length (up to 60 s), width and frame rate.
