Convert TIFF to JPEG

Turn TIFF, the high-fidelity raster format used in print and scanning, into JPEG, the ubiquitous compressed photo format from cameras and the web. FileChanger runs the image 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=tiff and to=jpg, 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 TIFF to JPEG 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.tiff" \
  -F "from=tiff" \
  -F "to=jpg" \
  -o output.jpg

import requests

    response = requests.post(
        "https://filechanger.io/api/convert",
        headers={"X-Api-Key": "fc_your_api_key_here"},
        files={"file": f},
        data={"from": "tiff", "to": "jpg"},
    )

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

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

  method: "POST",
  headers: { "X-Api-Key": "fc_your_api_key_here" },

Frequently asked questions

How do I convert TIFF to JPEG?

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

Is converting TIFF to JPEG 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 TIFF to JPEG 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.
