Frequently Asked Questions

How do I export a HAR file from my browser?
In Chrome, Firefox, or Edge, open DevTools (F12 or Cmd+Option+I), navigate to the Network tab, perform your actions, and click the 'Export HAR' arrow icon or right-click any request and select 'Save all as HAR with content'.
Is my HAR file uploaded to any remote server?
No. The HAR parser executes 100% client-side in your local browser sandbox. No cookies, auth tokens, or network payload data are ever sent over the internet.
How does the tool handle browser noise and telemetry headers?
By default, the tool automatically strips browser-specific client hints and fetch metadata headers (such as sec-ch-ua and sec-fetch-mode) and HTTP/2 pseudo-headers (:authority, :path) so your cURL commands remain clean and portable.
Can I filter requests by endpoint or HTTP method?
Yes. Use the 'Filter by Method' dropdown (GET, POST, PUT, DELETE, etc.) and 'Filter by URL' text box to isolate exactly the API endpoints you need.
