Question 1

How do I convert an MKV file to M4A?

Accepted Answer

Drag your MKV file onto the box above, or click Select file to choose it. Click Convert and wait for the progress bar to finish. Click Download to save the M4A file.

Question 2

Is M4A the right format for my MKV video?

Accepted Answer

M4A is the best choice when your MKV file has AAC sound, because that sound is copied exactly as it is. Films with Dolby Digital sound work well too: the sound is converted to AAC at 192 kbps, and 5.1 surround sound is kept. Choose MKV to MP3 only if an app or device doesn't accept M4A files.

Question 3

Does converting to M4A lose quality?

Accepted Answer

It depends on the sound in your MKV file. AAC sound is copied into an M4A file exactly as it is, with no quality loss. Other formats, such as Opus or Dolby Digital, are converted to AAC at 192 kbps, which is high quality for music and speech.

Question 4

Is 5.1 surround sound kept?

Accepted Answer

Yes. 5.1 sound stays as six channels in the M4A file. Phones and most headphones play it mixed down to stereo.

Question 5

Why isn't my video accepted?

Accepted Answer

This page accepts MKV files, whose names end in .mkv. Most other videos are MP4, MOV or WebM files. Check the end of the file name and use the matching converter: MP4 to M4A, MOV to M4A or WebM to M4A.
