Convert ISO to TAR

Turn ISO, the optical disc image format holding a full CD/DVD filesystem, into TAR, the Unix tape archive bundling files without compression. FileChanger runs the archive 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=iso and to=tar, 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 ISO to TAR 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.iso" \
  -F "from=iso" \
  -F "to=tar" \
  -o output.tar

import requests

with open("input.iso", "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": "iso", "to": "tar"},
    )

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

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

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

Frequently asked questions

How do I convert ISO to TAR?

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

Is converting ISO to TAR 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 ISO to TAR 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.
