Frequently Asked Questions

What is an HTTP Archive (HAR) file?
HAR (HTTP Archive) is a standardized JSON format defined by the W3C for logging a web browser's interaction with a server, containing detailed records of requests, headers, query parameters, cookies, and timings.
Can I import the generated HAR file into browser DevTools or Postman?
Yes. The generated HAR file conforms to the official HAR 1.2 specification and can be imported into Chrome, Edge, and Firefox DevTools Network panels, or imported into API tools like Postman, Insomnia, and Charles Proxy.
Can I convert multiple cURL commands at once?
Yes. You can paste multiple cURL commands separated by newlines. The converter will parse each command and generate a unified HAR archive containing all requests as distinct entries in the log.
