What is WMV?
WMV is a video container. Converting it changes how the video and audio streams are packaged so the clip plays where you need it.

Why convert WMV to MKV?
The usual reason to convert WMV to MKV is file size or quality: MKV fits the job better, whether that means a smaller download, a cleaner edit, or broader support. The conversion runs through ffmpeg, the industry-standard media engine, re-encoding the streams with sensible high-quality defaults so the result plays cleanly on your target device.
