What changes in this conversion

  • The picture and sound are re-encoded to H.264 video with AAC audio inside the AVI container, which is what makes the result play on the widest range of devices.

How to use

  1. Add your M2TS file

    Drag the M2TS file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. Confirm AVI as the output

    AVI is already selected as the output format on this page. You can pick the resolution. Encoding is the slowest part, so smaller resolutions finish sooner.

  3. Run the conversion

    Press the convert button. Video is re-encoded frame by frame on your own machine, so a long clip can take several minutes. The tab has to stay open.

  4. Download the AVI file

    When it finishes, download the AVI file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions

Is converting M2TS to AVI really free?

Yes. M2TS to AVI conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my M2TS files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the M2TS file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Is there a file size limit for M2TS to AVI conversion?

The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
