cURL Converter FAQ
Does the converter execute my cURL command?
No. The tool parses the command string and generates structured output or code. It does not run shell commands or make the HTTP request for you.
Can I paste cURL copied from Chrome or Firefox DevTools?
Yes. Browser “Copy as cURL” commands commonly include headers, cookies, compressed responses, redirects, and JSON bodies; those are the primary cases this tool is designed to parse.
Why is generated browser JavaScript different from cURL?
Browsers restrict some headers and cookie behavior for security. The generated fetch code is a practical starting point, but protected headers and cross-origin cookies may need app-specific handling.
Should I paste production tokens or cookies?
Avoid pasting live credentials into any online tool. Use redacted or test credentials when converting requests that contain Authorization headers, cookies, API keys, or session IDs.
