cURL to JavaScript Fetch Converter — Paste a Command, Get Working Code

Paste a cURL command — copied from browser devtools, an API doc, or a colleague's terminal — and get equivalent JavaScript fetch() code instantly, with headers, HTTP method and request body all correctly translated, instead of hand-converting each flag yourself.

How to use cURL to JS

1. Paste your cURL command.
2. Review the generated fetch() code.
3. Copy it into your JavaScript project.

Frequently asked questions

Where do I usually get a cURL command to convert?

Browser devtools' Network tab has a "Copy as cURL" option on any request — pasting that here is one of the fastest ways to turn a real network request into working fetch() code.

Does it handle custom headers and authentication?

Yes — -H header flags and common auth patterns in the cURL command are translated into the fetch() headers object.

What about a POST request with a JSON body?

The -d/--data body content and its Content-Type are correctly translated into the fetch() body and headers.
