About What Is My Browser
What Is My Browser shows the details every website can read about your browser, without you having to dig through settings. At the top you see your browser and its version, your operating system and version, and whether you are on a phone, tablet or computer. It recognises Chrome, Edge, Firefox, Safari, Opera, Samsung Internet and Brave, including Chrome and Firefox on iPhone and iPads that request desktop sites. In Chrome-based browsers it also reads the real operating system version (for example Windows 11, which the user-agent string reports as Windows 10) and the full browser version. Below that, the details are grouped: screen and window size, pixel ratio, dark or light mode and touch support; your languages and time zone; privacy settings such as cookies, Do Not Track and Global Privacy Control; CPU threads, approximate memory, graphics and connection type; and support for features such as WebAssembly, service workers, WebGL, clipboard access and the share sheet. One click copies everything as a neat summary to paste into a support ticket or bug report. All of it is read in your browser; nothing is sent to us.

Browser tips
Read the results correctly
User agents are reduced
Modern browsers send a simplified user-agent string; the real versions come from client hints when available.
Window is not screen
Websites lay out pages for the window size, not the screen size.
Screen Resolution CheckerUpdate your browser
Many site problems are fixed by updating to the latest version.
Clear cookies to test
A private window shows how a site behaves without your saved data.
Copy, don’t screenshot
A copied summary is easier for support to read than a screenshot.
