How to convert MTS to MP3
- Add your .MTS 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
- Audio is always re-encoded - AC-3 and PCM both require transcoding to MP3, so quality loss is unavoidable; use 192 kbps or higher for music.
- Video, chapter markers, and all metadata are discarded; only the audio track survives.
- AVCHD camcorders split long recordings into multiple numbered
.mtsfiles - process each separately or concatenate them first.
Frequently asked questions
Does converting MTS to MP3 lose quality?
Yes, always - the source audio (AC-3 or PCM) must be transcoded to MP3. The loss is small at 192 kbps and rarely noticeable for speech; use 256-320 kbps for music.
Is MTS the same as M2TS?
Effectively yes - both carry the same AVCHD stream, so any tool that handles
.mts works equally on .m2ts files.Can I extract audio without quality loss?
Not to MP3 - it is a lossy format. Use FFmpeg to export to WAV or FLAC instead if you need lossless audio.
My MTS file has two audio tracks - which one gets converted?
Most tools pick the first track by default. In FFmpeg, add
-map 0:a:0 to select it explicitly.Programs that convert MTS: Aimersoft iTransfer for Windows · Free Studio · Freemake Video Converter · MediaCoder · WinX Video Converter · Wondershare Video Converter for Mac · Aimersoft iTransfer for Mac
