What Is curlconverter.com?

Updated

curlconverter.com is a free browser-based utility that converts a cURL command into equivalent code in another language or HTTP client library. You paste a cURL command into the input box, choose a target language from the Language: dropdown, and the site generates code you can copy to your clipboard. It is useful when you have a working request captured from browser DevTools or documentation and want the same request expressed in Python, JavaScript, Go, or another stack.

What it does

The site's stated purpose is to convert cURL commands to Python, JavaScript, and more. The conversion is one-way: cURL in, code out. The page shows a live example — a simple curl request becomes:

import requests
response = requests.get(
    'http://example.com'
)

with a Copy to clipboard button beneath it.

Supported output languages and libraries

The Language: selector lists a broad range of targets, including:

Category Options
Python Requests, http.client
JavaScript fetch, jQuery, XHR
Node.js Axios, Got, Ky, node-fetch, request, SuperAgent, http
Java HttpClient, HttpURLConnection, jsoup, OkHttp
PHP cURL, Guzzle
Ruby Net::HTTP, HTTParty
R httr, httr2
PowerShell Invoke-RestMethod, Invoke-WebRequest
Other languages C, C#, Clojure, ColdFusion, Dart, Elixir, Go, Julia, Kotlin, Lua, MATLAB, Objective-C, OCaml, Perl, Rust, Swift
Other formats Ansible, HAR, HTTP, HTTPie, JSON, Wget

The list also includes a plain JSON output and an HTTP representation, which are handy when you want to inspect the request structure rather than run it in code.

How to use it

  1. Get a cURL command. The site documents three browser workflows:
    • Chrome: open the Network tab in DevTools, right-click a request, choose Copy → Copy as cURL (or Copy as cURL (bash)), then paste it into the curl command box.
    • Safari: open the Network tab in Developer Tools, right-click (or Ctrl-click / two-finger click) a request, choose Copy as cURL, then paste it.
    • Firefox: open the Network Monitor tab in Developer Tools, right-click a request, choose Copy → Copy as cURL, then paste it.
  2. Paste the command into the curl command box.
  3. Select your target from the Language: dropdown.
  4. Copy the generated code with the Copy to clipboard button.

The page notes that each browser's copy-as-cURL workflow also works in the other browsers listed, so you are not locked into one.

Common examples referenced on the page

The site links to example categories you can use as starting points: GET, POST, JSON, Basic Auth, Files, and Form. These cover the request shapes most people need to translate.

Things to watch out for

  • Sensitive data in copied commands. The site warns that a copied command may contain cookies or other sensitive data, and that sharing someone your cookie for a website is like sending them your password. Treat copied cURL commands as secrets.
  • Syntax errors. If the generated output looks wrong, the page directs you to open a new issue on GitHub rather than assume the conversion is correct.
  • Scope. The tool converts commands; it does not execute them or verify that the target server accepts the request. You still need to run the generated code in your own environment.

When to use it

Use curlconverter.com when you already have a cURL command — from browser DevTools, API docs, or a colleague — and need it in a language or library your project uses. It saves the manual work of mapping headers, query parameters, body encoding, and auth into a client library's API. If you only need to run the request as-is, you can just run the cURL command directly and skip the conversion.
