File Conversion API

Every tool on AllFreeConvert.com is available through one HTTP endpoint. Send a multipart/form-data POST and get JSON back with download links.

Endpoint

POST http://allfreeconvert.com/api/process.php

Parameters

Example

Conversions run in a queue, so the upload returns straight away with a job id:

curl -F tool=mp4-to-mp3 -F bitrate=192k -F "files[][email protected]" http://allfreeconvert.com/api/process.php
{ "ok": true, "job": "…", "status": "queued", "status_url": "/api/status.php?job=…" }

Then check status_url every 1–2 seconds. status goes from queued (waiting for a free slot) to processing, then done or error:

curl "/api/status.php?job=…"

{
  "ok": true,
  "status": "done",
  "files": [
    { "name": "video.mp3", "size": 3145728, "url": "/download.php?job=…&file=video.mp3" }
  ]
}

When a job produces several files (for example PDF → JPG), the first entry is a ZIP with everything. Download links expire after 8 hours. Errors return {"ok": false, "error": "…"}. Uploads are rate-limited; too many in a short time returns HTTP 429.
