Convert ISO to ZIP

Turn ISO, the optical disc image format holding a full CD/DVD filesystem, into ZIP, the universal archive format every operating system opens. 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=zip, 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 ZIP 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=zip" \
  -o output.zip

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": "zip"},
    )

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

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

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 ZIP?

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

Is converting ISO to ZIP 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 ZIP 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.
