Convert M2TS to AIFF

Turn M2TS, the Blu-ray flavour of the MPEG transport stream, straight off camcorders, into AIFF, Apple's uncompressed audio format, the Mac cousin of WAV. FileChanger runs the video conversion in one call, no local tooling to install.

In the browser

Upload a file and download the result, no pipeline required. Open the converter.

One API call

POST the file with from=m2ts and to=aiff, get the converted bytes back. Jump to the code.

From an agent

FileChanger ships an MCP server, so agents can run this conversion themselves. See the docs for setup.

Convert M2TS to AIFF in code

The same call from any language: POST the file to /api/convert, the response body is the converted file.

curl -X POST https://filechanger.io/api/convert \
  -H "X-Api-Key: fc_your_api_key_here" \
  -F "file=@input.m2ts" \
  -F "from=m2ts" \
  -F "to=aiff" \
  -o output.aiff

import requests

with open("input.m2ts", "rb") as f:
    response = requests.post(
        "https://filechanger.io/api/convert",
        headers={"X-Api-Key": "fc_your_api_key_here"},
        files={"file": f},
        data={"from": "m2ts", "to": "aiff"},
    )

response.raise_for_status()
with open("output.aiff", "wb") as out:
    out.write(response.content)

const formData = new FormData();
formData.append("file", fileInput.files[0]);
formData.append("from", "m2ts");
formData.append("to", "aiff");

const response = await fetch("https://filechanger.io/api/convert", {
  method: "POST",
  headers: { "X-Api-Key": "fc_your_api_key_here" },
  body: formData,
});

const output = await response.blob();

Frequently asked questions

How do I convert M2TS to AIFF?

Upload your file in the browser converter and pick AIFF as the target, or POST it to /api/convert with from=m2ts and to=aiff. The response body is the converted file.

Is converting M2TS to AIFF free?

Yes. The free tier includes 2 GB of conversions per month, metered on input size. See pricing for the paid tiers.

Is there an API for M2TS to AIFF conversion?

Yes, this whole conversion is one POST to /api/convert (the code examples above show it in five languages), plus an MCP server so AI agents can run it directly.
