Convert PDF to GIF

Turn PDF, the fixed-layout document format that looks the same on every device, into GIF, the classic animated image format that plays everywhere. FileChanger runs the document 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=pdf and to=gif, 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 PDF to GIF 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.pdf" \
  -F "from=pdf" \
  -F "to=gif" \
  -o output.gif

import requests

with open("input.pdf", "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": "pdf", "to": "gif"},
    )

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

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

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

About PDF

PDF is the fixed-layout document format that renders identically on every device, which is why it is the standard for invoices, papers, forms, and anything meant to be printed or archived. It is a publishing target rather than an editing format.

Frequently asked questions

How do I convert PDF to GIF?

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

Is converting PDF to GIF 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 PDF to GIF 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.
