Convert HTML to Jira Wiki

Turn HTML, the markup language of the web, readable by every browser, into Jira Wiki, the wiki markup used in Jira comments and descriptions. 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=html and to=jira, 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 HTML to Jira Wiki 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.html" \
  -F "from=html" \
  -F "to=jira" \
  -o output.jira

import requests

with open("input.html", "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": "html", "to": "jira"},
    )

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

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

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 HTML

HTML is the markup language of the web, rendered natively by every browser on every device. It is both a publishing target (turn any document into a web page) and a source format (turn saved pages and web content into editable documents).

About Jira Wiki

Jira wiki markup is the text formatting language used in Atlassian Jira issue descriptions and comments. Teams converting documentation or reports into Jira tickets use it to preserve headings, tables, and code blocks that Jira renders natively.

Frequently asked questions

How do I convert HTML to Jira Wiki?

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

Is converting HTML to Jira Wiki 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 HTML to Jira Wiki 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.
