Convert Textile to reStructuredText

Turn Textile, a lightweight markup language used by Redmine and older CMSes, into reStructuredText, the documentation format of the Python ecosystem and Sphinx. 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=textile and to=rst, 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 Textile to reStructuredText 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.textile" \
  -F "from=textile" \
  -F "to=rst" \
  -o output.rst

import requests

with open("input.textile", "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": "textile", "to": "rst"},
    )

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

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

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();

About Textile

Textile is a lightweight markup language that predates Markdown, still used by Redmine and a number of older content management systems. Teams maintaining or migrating legacy Redmine wikis and CMS content are its main users today.

About reStructuredText

reStructuredText (RST) is the documentation format of the Python world, consumed by Sphinx to build the docs of Python itself and thousands of libraries. Its directive system supports cross-references, API docs, and multi-page manuals beyond what plain Markdown offers.

Frequently asked questions

How do I convert Textile to reStructuredText?

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

Is converting Textile to reStructuredText 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 Textile to reStructuredText 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.
