HAR → .http converter

Drop a .har capture from your browser's DevTools Network tab and get clean, runnable .http requests — one per call, headers and bodies kept. It all happens in your browser: nothing is uploaded.

Drop a .har file here or browse — or paste below.

Converts automatically — nothing leaves your browser.

.http output
Your .http requests will appear here.

What it does

  • One ### request per captured call, in order
  • Full URL with query, every request header, and the request body
  • Rebuilds form bodies from postData.params
  • Only XHR/Fetch skips images, CSS, scripts, and fonts
  • Drops HTTP/2 :pseudo headers and (optional) sec-* noise
  • Pretty-prints JSON bodies

Get a HAR file

In your browser, open DevTools → Network, reproduce the calls, then right-click the list → Save all as HAR. Drop that file here. New to the .http format? Read the .http guide.

Have a spec instead? OpenAPI → .http

Common questions

How do I convert a HAR file to .http?

Drop or paste the .har above — it's parsed in your browser into one .http request per captured call (URL, headers, body), ready to copy or download as requests.http.

How do I capture a .har file?

Open DevTools → Network, reproduce the requests, then right-click the list → Save all as HAR. Use that file here.

Can I keep only API calls?

Yes. Only XHR/Fetch skips images, CSS, scripts, and fonts, and Trim browser-noise headers removes sec-* and similar noise.

Is my HAR file uploaded anywhere?

No. Everything runs in your browser — which matters because a HAR often carries the session's cookies and auth tokens. None of it leaves your machine.
