}Frequently Asked Questions
What cURL flags are supported?
Supports -X (method), -H (headers), -d/--data/--data-raw (body), -u/--user (basic auth), -F/--form (multipart), --compressed, -s (silent). Bearer token detection from Authorization header.
How do I get a cURL from browser DevTools?
In Chrome: DevTools → Network tab → right-click any request → Copy → Copy as cURL. Paste directly here. Works with all headers including cookies and auth tokens.
Does it support multiline cURL?
Yes — cURL commands with line continuation backslashes (\) across multiple lines are normalized and parsed correctly.
Is my API key safe?
Yes — all conversion runs in your browser. Nothing is sent to any server. Works completely offline once loaded.
How do I import the Postman JSON output?
Enable "Postman JSON" in the language toggles. Copy the output. In Postman: File → Import → Raw text → paste → Import. Your request is created as a collection item.
