Which Java version do I need?

Java 11 or later. `java.net.http.HttpClient` was finalized in Java 11. For older Java versions, pick `Java (OkHttp)` or `Java (Jsoup)` from the language picker.

Should I use HttpClient or OkHttp?

Use `HttpClient` (this page) for zero-dependency code on Java 11+. Pick OkHttp for projects already using it (very common in Android and many backend frameworks).

Does it support async / non-blocking requests?

Yes — `HttpClient` supports both `send()` (blocking) and `sendAsync()` (returns a `CompletableFuture`). The converter outputs the synchronous version by default.

How do I parse a JSON response?

Combine with Jackson (`ObjectMapper`) or Gson to deserialize `response.body()` into a Java class. The standard library doesn't include JSON parsing.

Is the conversion private?

Yes — everything runs in your browser.

How to copy a curl command from DevTools

Most browsers can export any network request as a ready-to-paste curl command.

Chrome / Edge

Open DevTools (F12 or Cmd/Ctrl + Shift + I)
Go to the Network tab and reload the page
Right-click a request → Copy → Copy as cURL

Firefox

Open the Network Monitor in DevTools
Right-click a request → Copy Value → Copy as cURL
Paste it in the input above

Safari

Enable the Develop menu in Settings → Advanced
Open Web Inspector → Network tab
Right-click a request → Copy as cURL

Your data stays in your browser

We never transmit, store, or log the curl commands you paste. All parsing and conversion happens client-side using JavaScript.

Watch for secrets

Curl commands copied from DevTools often contain cookies, bearer tokens, or API keys. Never share converted code without scrubbing those values first.

About converting curl to Java

Convert curl to Java using `java.net.http.HttpClient`, the modern HTTP client built into Java 11 and later. The generated code uses fluent builders, supports HTTP/2 by default, and provides synchronous and asynchronous request methods — all without external dependencies. Methods, headers, JSON bodies, and authentication from your curl command are preserved in idiomatic Java that's ready to drop into any Spring Boot, Micronaut, Quarkus, or plain Java project.

File extension: .java

How to use the Java output

1Paste your curl command above.
2Copy the generated Java snippet.
3Make sure you're on Java 11+ (`java -version`) — `HttpClient` is built in.
4Drop the code into a class with a `main` method, or use it inside an existing service.
5Compile with `javac` and run with `java`, or use your IDE's run button.
