Extract the audio from an MKV movie or episode and save it as MP3 - quickly and privately in your browser.

About this converter

MKV files often hold high-quality audio alongside their video - a film score, a concert recording, or the dialogue from an episode. MKV to MP3 lifts that audio out and saves it as a standard MP3 you can play anywhere.

Since MKV usually stores audio as AAC, AC-3, or DTS, the track is re-encoded to MP3 during extraction. The video is discarded; only the sound remains.

MKV to MP3: good to know

Multiple audio tracks: MKV can contain several language tracks - the primary track is extracted.
Bitrate: use 256-320 kbps for music and soundtracks; 128-192 kbps is fine for dialogue.
For lossless audio for editing, choose WAV instead of MP3.

Frequently asked questions

How do I convert MKV to MP3?

Drop your MKV file above, choose MP3 as the output, and click Convert, then Download. Only the audio is kept.

Which audio track gets extracted from a multi-track MKV?

The primary audio track is used. If your MKV has several language tracks, the main one is extracted to MP3.

Will the audio quality drop?

MP3 is lossy, so there is some loss, but at 256-320 kbps it is hard to notice. For a perfect copy intended for editing, extract to WAV instead.

Does this keep the video?

No - MKV to MP3 saves only the soundtrack. The video is discarded.

Is it private?

Yes. Extraction runs in your browser via WebAssembly, so the file never leaves your device.
