# curl to Java Converter

Paste a curl command, get working Java code using the built-in `java.net.http.HttpClient` — headers, bodies, auth, and redirects translated. Runs in your browser, no signup.

curl command

Conversion runs entirely in your browser — the command (and any tokens or cookies in it) is never sent to a server. Tip: DevTools Network tab → right-click a request → Copy as cURL.

```python

```

## Scraping a real site? Skip the blocks

Hand-copied curl headers go stale, and sites still block datacenter IPs. The same request through the WebScraping.AI API gets rotating proxies, headless Chrome rendering, and unblocking in one call — your custom headers and cookies are forwarded via the `headers` parameter. Shown with the [official client library](https://webscraping.ai/docs#sdks) of your choice:

```bash

```

## What the generated Java code does

The output targets `java.net.http.HttpClient`, standard since Java 11 — no Maven dependency needed: the builder pattern with `.uri(URI.create(…))`, a `.header(…)` call per `-H`, bodies via `HttpRequest.BodyPublishers.ofString`, `-u` as a precomputed Basic `Authorization` header, and `-L` as `.followRedirects(HttpClient.Redirect.NORMAL)` on the client builder — unlike curl, HttpClient does _not_ follow redirects by default.

Multipart uploads are the one real gap: `java.net.http` has no built-in multipart body, so the converter marks the spot and suggests OkHttp rather than generating fragile boundary boilerplate.

## Frequently asked questions

How do I convert a curl command to Java?

Paste the command into the converter above — it outputs java.net.http.HttpClient code instantly, in your browser. Headers, cookies, request bodies, basic auth, and redirect handling are translated. Nothing you paste is sent to a server.

HttpClient, OkHttp, or HttpURLConnection?

java.net.http.HttpClient (Java 11+) is the modern standard-library choice and needs no dependency — that's what the converter generates. OkHttp adds multipart bodies, interceptors, and HTTP/2 niceties. HttpURLConnection is legacy; avoid it in new code.

Which Java version does the generated code need?

Java 11 or newer — java.net.http shipped in 11, and every LTS since (17, 21) includes it. On Java 8 you'd need OkHttp or Apache HttpClient instead; the request structure translates one-to-one.

The Java code gets a 403 but curl works — why?

The JVM's TLS fingerprint differs from curl's and from real browsers, and anti-bot systems also weigh IP reputation and JavaScript challenges. Copied session cookies expire too. The WebScraping.AI API runs the same request through rotating proxies and real headless Chrome — one call from Java.
