Features
Key Features.
Paste any cURL
Paste cURL from browser DevTools, Postman, or the command line. GET, POST, headers, and JSON body supported.
JavaScript fetch()
Get clean, runnable fetch() code for browser or Node.js. Headers, method, and body are preserved.
One-click convert

Basic auth support

API and DevTools friendly
Ideal for converting network requests from Chrome DevTools or API docs into fetch code.
Where can I get a cURL command?
In Chrome or Edge: open DevTools (F12) → Network tab → perform the request → right‑click the request → Copy → Copy as cURL. In Firefox: same steps, then Copy as cURL. Postman and other API tools also offer “Copy as cURL”.
Does it support all cURL options?
It supports the most common options: -X / --request , -H / --header , -d / --data , -u / --user (Basic auth), -G / --get , and --url . Options like -k (insecure) or --compressed are not reflected in the fetch output.
Can I use the output in Node.js?
Yes. In Node.js 18+ the native fetch is available. For older Node, use a polyfill (e.g. node-fetch ) or run the code in the browser.
Why does my cURL not convert?
Ensure the command starts with curl and includes a valid URL (e.g. https://... ). Multi-line cURL is supported. If it still fails, simplify the command to the minimal form (e.g. curl 'https://api.example.com' ) and add options back one by one.
