Browser & Device Info

Discover what websites can learn about your device just from your browser: screen and window size, pixel ratio, languages, time zone, hardware threads, touch support, cookies status and more. Everything is read locally on this page — a handy tool for checking what your browser exposes and for debugging display issues.

All details are read locally by this page in your browser. Nothing is transmitted to us or anyone else.

About this tool

Every browser quietly shares certain details with websites — screen size, language, time zone and device capabilities — so pages can adapt. Most of it is harmless, but it is interesting (and useful) to see exactly what is exposed.

This page simply reads those same standard values and displays them for you, which is also handy when you need to report your setup for tech support.

Frequently asked questions

Is this information sent to your server?
No. The details are read by JavaScript running on this page in your own browser. Nothing is transmitted or logged anywhere.
Can websites really see all this?
Most of it, yes — screen size, language, time zone and user agent are standard web APIs used to make sites responsive. Exact hardware details vary by browser, and modern browsers increasingly round or limit them for privacy.
Why is my viewport smaller than my screen?
The viewport is the browser window’s content area, which shrinks when the window is not maximized or when toolbars and tabs take space. The screen size is your monitor’s full resolution.
What does pixel ratio mean?
It is how many physical pixels fit into one CSS pixel. A ratio of 2× or 3× means a high-density (retina) display, which is why images need to be supplied at double size to look sharp.
How do I share these details with tech support?
Press “Copy details” and paste the text into your support request — it includes everything a technician usually asks for.
