HAR File Viewer and Analyzer
Open HTTP Archive files and inspect requests, errors, sizes and timings
HAR files may contain cookies, Authorization headers, and request bodies. Do not share sensitive HAR files.
About this tool
HAR File Viewer and Analyzer opens an HTTP Archive exported by Chrome, Edge, Firefox, Safari, or another network client. It summarizes request count, HTTP errors, transferred bytes, and total recorded time, then provides a searchable table of methods, status codes, hosts, paths, MIME types, sizes, and durations. Select a request to inspect headers and generate a reproducible cURL command. HAR files can contain credentials and cookies, so the file is parsed only in your browser and never uploaded.
Frequently Asked Questions
What is a HAR file?
HAR is a JSON-based HTTP Archive format that records browser network requests and responses.
Which browsers can export HAR?
Chrome, Edge, Firefox, Safari, and many debugging tools can export network activity as HAR.
Can a HAR contain passwords or tokens?
Yes. It may include cookies, Authorization headers, query parameters, and request bodies, so handle it as sensitive data.
Can I convert a request to cURL?
Yes. Select a row and copy the generated cURL command from the request detail panel.
Does total time equal page load time?
No. The displayed total adds recorded request durations; overlapping requests mean it can exceed wall-clock load time.
Is the HAR uploaded?
No. The JSON file is read and analyzed locally in your browser.
