How to convert M2TS to MP3
- Add your .M2TS file - drop it in the box above or click to browse.
- Convert it to .MP3 in a few seconds.
- Download your new .MP3 file.
What to expect
- Only audio is kept - video, subtitles, and chapter markers are all discarded in the output
.mp3. - M2TS often carries lossless audio (Dolby TrueHD, DTS-HD MA); re-encoding to MP3 is a one-way lossy step - use 192-320 kbps to limit quality loss.
- Blu-ray M2TS files frequently contain multiple audio tracks (languages, commentary); FFmpeg selects the first by default - run
ffmpeg -i input.m2tsto list all available streams.
Frequently asked questions
Will the audio quality be good?
It depends on the bitrate you choose. The source is often high quality, but MP3 is lossy - 192-320 kbps is recommended. For lossless output, extract to FLAC instead.
How long does conversion take?
FFmpeg typically processes audio at 10-50x real-time, so a 2-hour file finishes in a few minutes on any modern machine.
Can I pick a specific language track?
Yes - in FFmpeg use
-map 0:a:1 for the second track, -map 0:a:2 for the third, and so on. Run ffmpeg -i input.m2ts first to see which track is which.What if FFmpeg says no audio stream was found?
If the file comes from a Blu-ray rip, try pointing FFmpeg at the full BDMV folder via its playlist file rather than a single
.m2ts clip.
