cURL Converter

What is cURL Converter?

cURL Converter transforms curl command-line requests into equivalent code for multiple programming languages and HTTP libraries including JavaScript fetch, Axios, Python requests, Go net/http, PHP cURL, Ruby Net::HTTP, and Java HttpURLConnection. It parses complex curl commands with headers, authentication, cookies, data payloads, and flags like --compressed, -L (follow redirects), and -k (insecure).

Developers implementing API integrations, technical writers creating multi-language code examples, and backend engineers converting prototype scripts to production code. The tool runs entirely in your browser — your data never leaves your device.

How to Use cURL Converter

1. Paste a curl command into the input field — including all flags, headers, and data
2. Select the target language and library from the output options
3. Review the generated code with proper imports, headers, and body formatting
4. Toggle options for error handling and response parsing in the generated code
5. Copy the code to paste into your application or script

Common Use Cases

• Converting curl examples from API documentation into fetch or Axios code for your application
• Translating browser DevTools Copy as cURL output into Python requests code for scripting
• Converting curl-based API examples from README files into Go or Java code
• Generating code snippets for multiple languages to include in SDK documentation
• Migrating shell-script-based API calls to proper application code in your language of choice

Pro Tips

• Copy the curl command from browser DevTools by right-clicking a request in the Network tab and selecting Copy as cURL — this captures all headers, cookies, and auth tokens exactly
• The -d flag in curl sends data as application/x-www-form-urlencoded by default — if you meant to send JSON, make sure the curl command includes -H 'Content-Type: application/json'
• Watch for -k or --insecure flag which disables SSL verification — the converted code should not disable SSL verification in production even if the original curl command did
