Browser Info Tool — IP, User Agent, Device, Screen & Features

About the Browser Info Tool

Ever wondered what your browser is telling the web about your device? This Browser Info Tool makes that information easy to see at a glance. It brings together the key details that websites can read in the background—like your browser and operating system, your public IP address, screen resolution, viewport size, and hardware hints—so you can understand what your setup looks like to a site or support team.

The tool works by reading standard browser signals and presenting them in plain language. You will see your User-Agent string (the text your browser sends to identify itself), plus modern structured data when available. It also reports GPU renderer, CPU core count, a device memory estimate, language and time zone, and whether features like cookies, local storage, Service Worker, WebRTC, and clipboard access are enabled. If your browser supports it, you will also get network hints such as connection type, effective speed, and round-trip time, which can explain slow page loads or streaming issues. Because some browsers reduce or mask details for privacy, results are best-effort, and we display the raw values so you can verify them.

Using the calculator is simple: open the page, wait a moment for the data to load, and scan the sections for the details you need. If you are resizing the window or switching devices, click Refresh to re-measure the viewport and time-sensitive fields. Use “Copy All” to paste your browser diagnostics into a support ticket, or choose “Export JSON” if you want a clean, structured report for debugging.

Real-world uses include troubleshooting web app compatibility, confirming device specs for graphics-heavy sites, checking why a responsive layout looks different, or sharing accurate system info with IT help desks. It is also handy for developers testing how a website behaves on different browsers, connection types, and screen sizes. Everything runs client-side, and aside from retrieving your public IP from a standard IP service, your data stays in your browser.
