What is a cURL to Fetch Converter?
A cURL to Fetch converter translates a cURL command — the classic Unix-style HTTP tool used in terminals — into equivalent JavaScript fetch() API code. This is one of the most common developer tasks when copying API calls from documentation, Postman exports, or browser DevTools "Copy as cURL" and adapting them for use in a JavaScript frontend or Node.js backend.
How to Convert cURL to Fetch
What cURL Options are Supported?
This converter handles the most common cURL flags: -X / --request for the HTTP method, -H / --header for custom headers, -d / --data / --data-raw for the request body, and -u / --user for Basic Authentication. The URL is automatically extracted from the command with or without quotes.
100% Private and Client-Side
All conversion runs locally in your browser. Your API keys, bearer tokens, request payloads, and endpoint URLs are never sent to any server. This is critical for converting cURL commands containing sensitive credentials from internal APIs, staging environments, or private microservices.
