Convert MTS to MP4 Online

Pick one or more MTS or M2TS files from your camera and convert them to MP4 in your browser. There is nothing to install and no account to create. The tool reads the file, changes its format and writes a standard MP4 you can share or edit.

No Upload Required

Every MTS file is processed on your own device. The browser reads the file locally and the MP4 is written either to a location you choose or downloaded directly. No server receives your footage and the tool keeps working with the network disconnected.

No Quality Loss

Most MTS camera files convert without any change to video quality. The converter changes the file format, not the video. If a file needs extra processing, the plan shown before converting says so.

What Is an MTS File?

MTS is the file format used by many camcorders and video cameras. It stores the recorded video and audio, but many phones, TVs and programs cannot open it without conversion.

MTS vs MP4

MTS is the recording format used by many cameras. MP4 is accepted by more devices, websites and programs. Converting makes camera footage easier to play and share.

Is MTS to MP4 Lossless?

For most files the conversion changes only the format, so the video stays exactly the same. If a file needs extra processing, the converter shows what it will do before you start.

Can I Convert Large MTS Files?

Camera files are often very large. The converter works with large files directly on your device, so there is no upload limit. Practical limits come from your computer and browser.

Supported MTS formats

The converter works with the video and audio formats used by most cameras, including 1080p, 1080i and 720p footage. A small number of camera files store audio in a way the converter cannot read. Those files convert without the audio. The queue explains when this happens.

MTS vs M2TS

MTS and M2TS are both camera video formats that work the same way. M2TS is more often linked to Blu-ray, while MTS is typical of camcorders. This converter accepts both.

Not for most camera files. The converter changes the file format and keeps the video itself unchanged. If a file needs extra processing, the plan shown before converting says so.

Are my videos uploaded?+

No. Conversion is performed locally in the browser. Your files never leave your device.

Can I convert large MTS files?+

Yes, provided the browser supports the required local file APIs and sufficient local storage is available. Large files stream directly to the destination instead of being held in memory. Chrome and Edge support this today.

Does converting change my original file?+

What about 1080i interlaced footage?+

Interlaced video from 1080i cameras is kept exactly as recorded.
