Paste from docs or from Chrome, Edge or Firefox DevTools (Copy as cURL, bash or cmd). Nothing is sent anywhere.
JavaScript fetch
const res = await fetch("https://api.example.com/users", { method: "POST", headers: { "Content-Type": "application/json", "Authorization": "Bearer abc123" }, body: JSON.stringify({ "name": "Ada Lovelace", "role": "admin", "active": true }) }); const data = await res.json(); console.log(res.status, data);
What the command does
- Request
- POST https://api.example.com/users
- Headers
- Content-Type, Authorization
- Body
- 52 bytes
How to use
01
Paste a curl command
Paste the command into the box, or press an example. Backslash and caret line breaks, single and double quotes, and the $'...' strings from Chrome's Copy as cURL are all understood.
02
Pick a language
Press one of the popular languages, or choose any of the 19 targets from the menu. The code updates as you edit the command. What the command does summarizes the parsed method, URL, headers and options.
03
Copy or download the code
Press Copy or Download. Replace placeholders such as fileInput for form uploads, and move secrets like bearer tokens into environment variables before you commit anything.
Why cURL to Code Converter
- 19 targets, from fetch and Python to Go, Java, C#, Rust, PHP, PowerShell and HTTPie.
- Understands -X, -H, -d and its variants, --json, -F, -u, -b, -G, -I, -k, -L, -m, -x and --compressed.
- Reads Chrome's Copy as cURL in both bash and Windows cmd formats.
- Converts live in your browser, so API keys in the command stay on your device.
Supported curl flags
The converter covers the flags that change what is sent. Anything else is ignored, so check the generated code if your command depends on an option that is not listed here.
| Flag | Meaning in curl | In the generated code |
|---|---|---|
| -X, --request | Set the HTTP method | method: "PUT" or requests.request("PUT", ...) |
| -H, --header | Add a request header | Entry in the headers object or dictionary |
| -d, --data, --data-raw, --data-binary | Send a request body, joined with & if repeated | body, data, json= in Python, or the body option in each language |
| --data-urlencode | URL-encode the value before sending | Encoded text added to the body |
| --json | Send JSON with JSON Content-Type and Accept headers | Both headers plus a JSON body |
| -F, --form | Multipart form field or file upload | FormData, or data= and files= in Python |
| -u, --user | Basic authentication | Authorization header, auth option in axios, auth= in Python |
| -b, --cookie | Send cookies | Cookie header |
| -A, -e | User-Agent and Referer | Matching headers |
| -G, --get | Put the data in the query string | Data appended to the URL |
| -I, --head | Send a HEAD request | method: "HEAD" |
| -k, --insecure | Skip TLS certificate checks | verify=False in Python, a comment in JavaScript |
| -L, --location | Follow redirects | Redirect option where the library needs one |
| -m, --max-time | Give up after N seconds | Timeout setting in each language |
| -x, --proxy | Send through a proxy | Proxy setting, or a comment |
| --compressed | Ask for and decode gzip | Decompression option in PHP, C# and wget; automatic elsewhere |
Output targets
Each target writes idiomatic code for its library. Pick the one your project already uses, so no new dependency is needed.
| Group | Targets |
|---|---|
| JavaScript | fetch (browser), axios, Node.js fetch |
| Python | requests |
| PHP | cURL extension, Guzzle |
| Other languages | Go net/http, Java HttpClient, C# HttpClient, Ruby Net::HTTP, Rust reqwest, Swift URLSession, Kotlin OkHttp, Dart http |
| Command line | PowerShell Invoke-WebRequest, HTTPie, wget |
| Other formats | Raw HTTP request, JSON request details |
Common questions
Which curl flags does the curl to code converter support?
It handles -X, -H, -d, --data, --data-raw, --data-binary, --data-urlencode, --json, -F, --form-string, -u, -b, -A, -e, -G, -I, -k, -L, -m or --max-time, -x or --proxy, --compressed and --url. Flags that do not change the request, such as -s, -v and -i, are ignored, and flags that take a value without affecting the request, such as -o, are skipped with their value.
How do I copy a request as cURL from Chrome DevTools?
Open DevTools, go to the Network panel, right-click the request, then choose Copy and Copy as cURL. Both the bash and the cmd versions work here; the converter removes the caret escapes that the Windows cmd version adds. DevTools includes every header the browser sent, so delete cookies and sec-fetch headers you do not need.
Why did my converted curl request switch from GET to POST?
That matches curl: sending data with -d, --json or -F implies POST unless you set another method with -X. With -G, the data is added to the URL as a query string and the method stays GET.
Why does the Python code use json= instead of data=?
When the Content-Type header says JSON and the body parses as JSON, the tool passes it as json=payload so requests serializes it for you. Any other body is passed as data= exactly as written in the command.
What happens to a curl command without http:// or https://?
The converter adds http:// in front, which is what curl does by default. Change it to https:// in the code if the server expects a secure connection.
How are file uploads with -F converted to code?
Text fields are appended to a FormData object in fetch and axios, or put in a data dictionary in Python. A field like avatar=@photo.jpg becomes fileInput.files[0] in JavaScript, which you replace with your own file object, and open("photo.jpg", "rb") in Python's files= argument.
Why did the fetch code add a Content-Type header I did not write?
curl sends -d data as application/x-www-form-urlencoded unless you set a Content-Type. The fetch API would label a plain string body as text/plain, so the converter adds the form header to keep the request identical.
Does the curl converter handle -k or --insecure?
Yes, in the way each language allows: verify=False in Python, InsecureSkipVerify in Go, a certificate callback in C#, danger_accept_invalid_certs in Rust, CURLOPT_SSL_VERIFYPEER in PHP, -SkipCertificateCheck in PowerShell and --verify=no in HTTPie. Where a language has no simple switch, such as fetch, a comment explains the option. Only skip certificate checks for local testing.
Can the curl converter write PHP, Go or Node.js code?
Yes. PHP comes in two styles, the cURL extension and Guzzle. Go uses net/http, and Node.js uses the built-in fetch, with openAsBlob for file uploads. Java, C#, Ruby, Rust, Swift, Kotlin, Dart and PowerShell are in the language menu too.
Is the curl command sent to a server during conversion?
No. Parsing and code generation run as JavaScript in your browser tab. That matters because copied commands often contain live API keys and session cookies.
