What is MKV?
MKV (Matroska) is an open, royalty-free container that can hold any number of video, audio and subtitle tracks plus chapters in a single file. It is popular for films and archives, but many phones, TVs and editors do not open it natively.
What is WAV?
WAV stores audio as uncompressed PCM, exactly as it was recorded. That makes it the standard for recording, editing and mastering, where no quality can be lost, but a WAV file is about ten times larger than the same audio in MP3.
Tips for converting MKV to WAV
- Only the soundtrack of your MKV file goes into the WAV; the picture is discarded.
- WAV keeps the soundtrack without further loss, but the file is several times larger than an MP3.
- Long videos still take a while to process, and the MKV upload itself must fit the 50MB free limit.
- Keep the original video: the audio file cannot be turned back into it.
