MTS to MP2 Converter
Processing entirely on your device — large files may take a moment.
MTS is the raw AVCHD clip format Sony/Canon camcorders write — high-bitrate H.264 transport streams straight off the memory card. Broadcast MP2 files convert to MP3 for players that no longer ship the decoder.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the MTS format
MTS is what actually comes off a Sony or Canon AVCHD camcorder's memory card: high-bitrate H.264 transport streams with AC-3/PCM audio, often split across a BDMV folder structure. The video inside is excellent — the container is what edit software refuses to import.
Converting MTS to MP4 remuxes or re-encodes into a container every device opens. Stream-copy is possible when the H.264 profile is baseline-compatible; otherwise a light re-encode fixes compatibility without visible loss.
+ Strengths
- ✓Native camcorder quality (24-28 Mbps)
- ✓Audio in AC-3/PCM survives remux
- ✓ffmpeg handles the transport stream natively
! Limitations
- −AVCHD H.264 profiles not always stream-copyable
- −Interlaced variants need deinterlacing
- −60p modes confuse older editors
About the MP2 format
MP2 (MPEG-1 Audio Layer II) is MP3's older, simpler sibling — and despite losing the consumer war, it never left broadcasting: digital TV (DVB), DVD-audio tracks and European radio still transmit MP2 daily. Its decoder is trivial, which is exactly why broadcasters love it.
Consumer devices have quietly dropped the decoder, so MP2 files from TV recordings or radio captures need conversion to MP3 for anything portable. The audio itself is often 256–384 kbps — genuinely good quality hiding in a forgotten format.
+ Strengths
- ✓The broadcast standard — still transmitted daily
- ✓Often high bitrate (256–384 kbps)
! Limitations
- −Dropped by consumer players
- −Less efficient than MP3 at equal quality
Why convert MTS to MP2?
Converting makes sense where the strengths of MP2 meet what MTS cannot give you. The broadcast standard — still transmitted daily Meanwhile AVCHD H.264 profiles not always stream-copyable One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this MTS to MP2 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for MTS to MP2?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of MP2, staying in sync with the video. If your MTS file has multiple audio tracks, the first one is used.
Does converting MTS to MP2 re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
