cURL → C# converter

Paste a curl command — including your browser's Copy as cURL (bash) — and get ready-to-paste C# HttpClient code. It all happens in your browser: nothing is uploaded.

Converts automatically as you type — nothing leaves your browser.

Your C# code will appear here.

What it does

  • Emits HttpClient + HttpRequestMessage code (.NET 8+)
  • Understands methods (-X), headers (-H), cookies, user-agent
  • Bodies (-d, --data-raw, --json) as StringContent
  • Basic auth (-u) → an Authorization header
  • Parses your browser's Copy as cURL (bash) output

Keep the request, not just the code

Code goes stale the moment the endpoint changes. Keep the request as a .http file you can re-run and diff — convert cURL → .http instead, or open it in Karve.

Common questions

How do I convert a cURL command to C#?

Paste the command above — it's parsed in your browser into ready-to-paste C# using HttpClient and HttpRequestMessage, with method, URL, headers, and body filled in.

Which C# HTTP client does the output use?

Modern HttpClient built around an HttpRequestMessage, with JSON bodies as StringContent using raw string literals (.NET 8+).

Does it handle headers, auth, and JSON bodies?

Yes — -H headers, -u Basic auth, and -d/--json bodies all carry through, including a browser "Copy as cURL".

Is my cURL command uploaded anywhere?

No. Conversion runs entirely in your browser — nothing you paste, including tokens, leaves your machine.
