What does cURL → JavaScript actually do?

cURL to fetch translates a curl command into a JavaScript fetch call. Method, URL, headers, and body are copied when the flags are ordinary. Exotic curl flags (--resolve, --unix-socket, --http2 specifics) are not fully mapped. The original command is parsed locally.

Are Authorization headers uploaded?

No. Conversion runs locally. Still avoid sharing production secrets in screenshots or chats.

Is every cURL flag supported?

Common request shapes convert cleanly. Exotic flags may need manual tweaks in the generated fetch.
