Convert M2TS to MP4.
M2TS (and MTS) is what AVCHD camcorders and Blu-ray recordings save in — high quality, but awkward to play and edit. Convert it to MP4 that works in any player and editor.
Great footage, fussy container
If you've copied video off an AVCHD camcorder, you've got a folder of .m2ts or .mts files — broadcast-grade transport streams that hold genuinely high-quality HD video. The problem is that the transport-stream container was designed for broadcasting, not editing, so consumer players and editors often stumble on it. MP4 holds the same H.264 video in a container everything understands.
Edit-ready
Once it's MP4, the footage drops cleanly into any editor — Premiere, Resolve, iMovie, CapCut — without the import errors and audio-sync quirks M2TS is notorious for. A good first step before you start a project from camcorder footage.

Common questions
What is an M2TS file?+
M2TS is the MPEG-2 Transport Stream container used by AVCHD camcorders and Blu-ray discs (the same footage often appears as .mts on the camera's memory card). It holds high-quality H.264 video, but the container itself trips up a lot of players and editors.
Will I lose quality?+
The video inside is usually already H.264, so converting to MP4 mostly re-wraps it — quality is preserved very closely while compatibility jumps to universal.
Is it free?+
Yes — convert M2TS to MP4 free, with no signup. Paid plans add larger files and bigger batches.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
