JSONP executes JavaScript and is not a modern substitute for CORS. Only use output with a trusted endpoint and callback consumer.

Private by design. Input is processed inside this browser tab and is not sent to ToolsOnDuty.

Frequently asked questions

Is my input uploaded?
No. This website tool runs in your browser. Only the optional public API version sends input to the authenticated API route.
Can I use this in an application?
Yes. The Developers documentation lists the authenticated endpoint, request parameters and response example.
Should I verify the result?
Yes. Deterministic tools are designed for repeatable results, but format-specific or heuristic output should still be checked for your use case.
