What is the difference between cURL and Fetch?

cURL is a command-line tool that runs in the terminal and supports dozens of protocols. Fetch is a browser-native JavaScript API (also available in Node.js 18+) for making HTTP requests in code. cURL is great for quick manual API tests; Fetch is what you use when integrating those same requests into a JavaScript application. This converter translates cURL commands into Fetch (or Axios) code automatically.

How do I import a cURL command into Postman?

In Postman, open a new request and click the "Import" button (or use File → Import). Choose "Raw text", paste your cURL command, and Postman will parse it into a full request with method, URL, headers, and body. Alternatively, use the cURL Converter on this page to export a Postman collection JSON you can import directly.

How do I convert a cURL command to JavaScript fetch?

Paste your cURL command into the converter and select JavaScript (fetch) as the target. The tool maps -X to the method option, -H flags to the headers object, and -d to the body. Authorization headers and cookies are preserved. The output is ready to paste into any browser JavaScript or Node.js 18+ project.

How do I convert cURL to Axios?

Select Axios as the target language after pasting your cURL command. The converter generates an axios.request() call with the correct method, url, headers, and data properties. Bearer tokens are placed in the Authorization header, and JSON bodies are automatically set as the data property with the correct Content-Type.

How do I convert cURL with cookies to code?

Cookies in cURL are specified with the -b flag (e.g. -b 'session=abc123'). The converter translates these into the appropriate cookie-sending mechanism for each language: a Cookie header in fetch, the cookies parameter in Python requests, or the appropriate cookie jar in other languages. Session cookies are preserved exactly.

How do I convert a cURL command to Python?

Paste your cURL command and select Python (requests). The tool generates clean Python code using the requests library, mapping each flag: -X becomes the method, -H flags become the headers dict, -d becomes json= or data=, and -u becomes auth=. The output includes an import requests statement and is ready to run.

How do I convert cURL to Java?

Select Java as the target language to get code using Java 11+ HttpClient. The converter generates a HttpRequest.newBuilder() chain with all headers added via .header() calls and the body set via HttpRequest.BodyPublishers. The output uses Java's built-in HTTP client — no external dependencies required.

What Is a cURL Command?

cURL (Client URL) is a command-line tool for sending HTTP requests and transferring data over the internet. It is pre-installed on macOS and Linux and is the go-to tool for developers testing APIs, debugging network calls, and scripting HTTP interactions from the terminal.

A cURL command is built from a URL plus a set of flags that describe the request. The most common flags are: -X to set the HTTP method (GET, POST, PUT, DELETE, PATCH), -H to add a request header, -d to attach a request body or JSON payload, and -u for basic authentication credentials. Together these flags fully describe any HTTP request — which is why converting cURL to code is so useful for integrating an API call you tested in the terminal into your application.

How it works

Convert cURL to Code in Seconds

Paste your cURL command

Copy the cURL command from your terminal, browser DevTools, API docs, or Postman and paste it into the input field.

Pick your target language

Select from Python, JavaScript Fetch, JavaScript Axios, PHP, Go, Java, Ruby, Rust, and more.

Copy the generated code

The converter instantly produces clean, idiomatic code with all headers, auth, and body correctly translated.

Run it in your project

Paste the snippet into your codebase. No manual translation, no missed flags, no syntax errors.

Supported Languages & Frameworks

The converter handles all major HTTP client libraries across the most popular programming languages:

Language	Library / Framework	Notes
Python	`requests`	Most popular Python HTTP library
JavaScript	`fetch` / `axios`	Works in browser and Node.js
PHP	`curl`	Native PHP cURL extension
Go	`net/http`	Standard library HTTP client
Java	`HttpClient`	Built-in since Java 11
Ruby	`Net::HTTP`	Standard library HTTP module
Rust	`reqwest`	Ergonomic async HTTP client

Common cURL Flags Explained

Understanding the flags in a cURL command makes it easier to read and convert them correctly:

Flag	Purpose	Example
-X	HTTP method	`-X POST`
-H	Request header	`-H "Content-Type: application/json"`
-d	Request body / data	`-d '{"key":"value"}'`
-u	Basic auth credentials	`-u user:password`
--data-urlencode	URL-encode a form field	`--data-urlencode "q=hello world"`
-b	Send cookies	`-b "session=abc123"`
-k	Skip TLS certificate check	`-k` (insecure, use only in dev)
-v	Verbose output	Shows request/response headers in terminal

FAQ

Frequently Asked Questions

1What is a cURL command?

cURL (Client URL) is a command-line tool for sending HTTP requests. It is used to test API endpoints, download files, and debug network calls from the terminal. A cURL command specifies a URL plus flags for the method, headers, body, and authentication.

2How do I convert cURL to Python?

Paste your cURL command into the converter above and select Python (requests) as the target language. The tool will generate the equivalent Python code with all headers, body, and auth correctly translated.

3Does the converter support authentication?

Yes. Basic auth (-u flag), Bearer tokens in Authorization headers, and API key headers are all correctly parsed and translated into the appropriate pattern for the target language.

4Is my cURL command sent to a server?

No. All conversion happens entirely in your browser. Your cURL commands — which may contain auth tokens or API keys — never leave your device.

5Can I convert cURL to Postman?

Yes. You can import a cURL command directly into Postman by clicking Import and pasting the raw cURL text. Postman will parse the method, URL, headers, and body automatically. You can also use the export feature in this converter to generate a Postman-compatible collection.

6What languages can I convert cURL to?

The converter supports Python (requests), JavaScript fetch, Axios, Go (net/http), Java (HttpClient), PHP (cURL extension), Ruby (Net::HTTP), Rust (reqwest), C#, Swift, Kotlin, and PowerShell. All output preserves the full request including headers, authentication, and body.

7How do I convert a cURL command from Chrome DevTools?

In Chrome DevTools, open the Network tab, right-click any request, and select Copy → Copy as cURL. This gives you a complete cURL command with all headers, cookies, and body exactly as the browser sent them. Paste it directly into this converter to generate the equivalent code in your target language.

8What does the -k flag do in curl?

The -k or --insecure flag skips TLS certificate verification — useful for local development with self-signed certs. Never use it in production as it removes protection against man-in-the-middle attacks. The converter notes when -k is present and preserves it in the output with a warning comment.

9Does the converter support file uploads?

Yes. File upload commands using -F (multipart/form-data) are converted to FormData in JavaScript or the files parameter in Python requests. Binary file paths from the original cURL command are preserved in the generated code.

10What is the difference between -d and --data-raw in curl?

Both send data as the request body, but -d treats @filename as a file reference while --data-raw sends the string literally without processing. Chrome DevTools uses --data-raw to ensure the body is sent verbatim. Both are correctly parsed and converted by this tool.

11How do I convert cURL to PHP?

Select PHP as the target language. The converter generates PHP code using the native cURL extension (curl_init, curl_setopt, curl_exec) with all headers, body, and options correctly mapped. The output includes error handling and curl_close() for proper resource management.

12How do I get a cURL command from Postman?

In Postman, open a request and click the </> Code button in the right panel. Select cURL from the language dropdown. Copy the generated command and paste it into this converter to translate it to any other language.
