About HAR Analyzer
The HAR Analyzer summarizes a HAR file into useful metrics: total requests, total transfer size, total time, plus a breakdown of status codes (200, 404, …) and content types (html, image, script, …). Useful for a quick page-performance audit.
Native parsing; in the browser.
FAQ
Are any network requests sent?
No. This tool only transforms/analyzes text in your browser — no actual HTTP request is sent, and your data never leaves your device. (Tools that truly call an external server are intentionally not provided due to browser CORS limits.)
Is my data safe?
Yes. All processing happens entirely locally in your browser. Nothing is uploaded, logged, or stored on our servers.
