The short answer
Convert MKV to MP4 when a device, app, or website does not accept MKV. MP4 is commonly accepted, but you should still test the final file before you share it.
Why change MKV to MP4?
MKV is flexible and can hold several tracks. Some devices and websites prefer MP4 instead.
You may want MP4 when you need to:
- play a video on a phone or TV app
- upload a video to a service that asks for MP4
- share a file with someone using a simple media player

What to check after conversion
A container conversion can still meet a codec limit. In simple words, the video or audio inside the file may affect whether a device can play it.
Check these items:
- Can your target device open the file?
- Does the picture play smoothly?
- Is the correct audio track present?
- Are subtitles available if you need them?
