FAQ

Does it handle auth headers?

Yes. Headers in the cURL command are translated into fetch headers.

Can I generate Axios instead?

Yes. The converter supports multiple output targets including Axios.

Is my cURL command stored?

No. The conversion happens locally in your browser.

What about multi-line cURL?

Paste it as-is; the converter handles typical line breaks.
