How to convert MTS to MP4 online

Open an MTS or M2TS file from a Sony, Panasonic, or Canon camcorder and export an MP4. The MTS to MP4 converter copies the H.264 video without re-encoding and converts the Dolby Digital audio, which browsers and many apps can't play, to a format they can.

  1. Step 1

    Choose your MTS
    Pick a file or drop it into the converter above.

  2. Step 2

    Keep MP4
    MP4 is selected; choose another format if you need one.

  3. Step 3

    Download the MP4
    Save the MP4 when the conversion finishes.

What to expect

Supported inputs
AVCHD .MTS and .M2TS files, other MPEG transport streams, and readable video files.
What happens
The H.264 video is copied unchanged, including interlaced 1080i footage. Dolby Digital (AC-3) audio is decoded and re-encoded, usually to AAC.
Limits
Each MTS clip converts on its own; long recordings split by the camera into several files need Combine videos. Subtitle tracks are left out.
