Question 1

How do I convert an MKV file to FLAC?

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 FLAC file.

Question 2

Is FLAC the right format for my MKV video?

Accepted Answer

FLAC is worth it when your MKV file has lossless sound, such as FLAC or PCM, or when you plan to edit or archive the sound. FLAC keeps every bit, and 5.1 surround sound stays as six channels. For films with Dolby Digital sound, FLAC gives a much bigger file that doesn't sound any better than MKV to M4A.

Question 3

Is 5.1 surround sound kept?

Accepted Answer

Yes. The FLAC file keeps all six channels, with nothing lost.

Question 4

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 FLAC, MOV to FLAC or WebM to FLAC.
