About cURL to Fetch

cURL to Fetch converts the cURL commands you copy from API docs, Postman or your browser’s network tab into ready-to-use JavaScript fetch() code.

Paste the command on the left and a clean, modern async/await snippet appears on the right, complete with the right HTTP method, headers and request body — no manual translation required.

The converter understands the cURL flags you actually meet in practice: -X / --request for the method, -H / --header for headers, -d / --data and its variants for the request body, and -u / --user for basic authentication, which it turns into a base64 Authorization header.

When you supply data without a method it infers POST, matching cURL’s own behaviour, and it quietly ignores transfer-only flags such as --compressed, -L and -k that have no meaning in the browser.

Multi-line commands with trailing backslashes are stitched together automatically, and quoted values keep their contents intact.

Everything runs locally in your browser, so the commands you paste — which may contain tokens or credentials — never leave your machine.

Use it to port a quick API example into a front-end app, to sanity-check what a cURL command really does, or to teach yourself the fetch API by example.

Copy the generated code with one click and drop it straight into your project.

FAQ

Which cURL flags are supported?

It handles -X/--request, -H/--header, -d/--data (and --data-raw/--data-binary) and -u/--user. Transfer-only flags like --compressed and -L are ignored because they have no fetch equivalent.

Is my command sent anywhere?

No. The conversion runs entirely in your browser, so any tokens or credentials in the command stay on your machine.

What if the command does not start with curl?

The tool expects a command beginning with “curl” and will show a friendly error otherwise, so you know to paste the right thing.
