cURL to Fetch Converter

Convert cURL commands to JavaScript Fetch API code. Paste any cURL command from API documentation, browser dev tools, or Postman exports and get clean, ready-to-use fetch() code. Automatically handles headers, request methods, and JSON body data.

Why Convert cURL to Fetch?

cURL is the universal language of API documentation. Almost every API provides cURL examples for testing endpoints. However, when building web applications, you need JavaScript code. Our converter bridges this gap by transforming cURL commands into clean, modern Fetch API code.

The Fetch API is the modern standard for making HTTP requests in JavaScript, supported by all major browsers. Unlike older XMLHttpRequest, Fetch uses Promises and provides a cleaner, more intuitive syntax for handling network requests.

Supported cURL Options

  • -X / --request: HTTP method (GET, POST, PUT, etc.)
  • -H / --header: Custom headers
  • -d / --data: Request body data
  • URL: The endpoint URL

Copy from Chrome DevTools

Did you know you can copy any network request as cURL from Chrome DevTools? Right-click any request in the Network tab, select "Copy as cURL", paste it here, and get instant JavaScript code. This is incredibly useful for replicating API calls you see in web applications.
