Browser Info
See what your browser tells websites: screen and window size in CSS pixels, pixel ratio, time zone, languages, processor count and user agent. How it works
Use the Browser Info
- Browser language
- -
- The first language in your browser settings.
- Time zone
- -
- The time zone your device is set to.
- Platform string
- -
- A legacy field that browsers keep fixed for compatibility: it does not reliably name your operating system (64-bit Windows reports Win32, Apple silicon reports MacIntel).
- Vendor string
- -
- A legacy field; it often reads Google Inc. in Chromium-based browsers and Apple Computer, Inc. in Safari.
- Logical processors (reported)
- -
- Logical processors the browser may use, not physical cores. A browser may report fewer than the device has.
- Device memory (reported)
- -
- Rounded to a power of two and capped; not available in every browser.
- Screen size
- -
- In CSS pixels, not device pixels. Multiply by the pixel ratio for an estimate of the panel.
- Device pixel ratio
- -
- Device pixels per CSS pixel; browser zoom changes it.
- Window size
- -
- The visible page area; it changes when you resize the window.
- Touch points
- -
- The most simultaneous touches the device reports; 0 means no touch screen is reported.
- Cookies enabled
- -
- Whether the browser accepts cookies at all; it does not say which sites you have allowed.
- Do Not Track (deprecated)
- -
- An old, non-standard setting that most sites ignore.
- Online
- -
- What the browser believes about its network connection.
This tool reads these values in your browser and does not send them anywhere or store them. The site itself keeps your recent tools and visit streak in this browser (localStorage). Every website you open can read the same values, and some combine them to recognise a browser (fingerprinting). This page only shows you what a site could see; it does not hide anything.
About the Browser Info
Every website can read the values on this page from your browser: screen and window size in CSS pixels, device pixel ratio, time zone, language list, the logical processor count, a rounded memory figure, touch points, the cookie, Do Not Track and Global Privacy Control settings, and the user agent string. Each value appears exactly as the browser reports it.
Example: the fields as the page shows them
| Field | Example value |
|---|---|
| Browser language | en-US |
| Language preference list | en-US, en |
| Time zone | America/New_York |
| Platform string | Win32 |
| Platform (client hints) | Windows |
| Browser brands (client hints) | Chromium 141 |
| Mobile browser (client hints) | No |
| Vendor string | Google Inc. |
| Logical processors (reported) | 8 |
| Device memory (reported) | about 8 GB (rounded and capped by the browser) |
| Screen size | 1536 x 864 CSS pixels |
| Device pixel ratio | 1.25x |
| Window size | 1536 x 730 CSS pixels |
| Touch points | 0 |
| Cookies enabled | Yes |
| Do Not Track (deprecated) | Not set |
| Global Privacy Control | Off |
| Online | Yes |
A Windows laptop at 125% display scaling in a Chromium-based browser. A browser that does not offer a value shows Not reported by this browser, and the client-hint rows appear only where the browser offers them.
Frequently asked questions
- What is my screen resolution in pixels?
- The page shows the screen size in CSS pixels, the unit websites lay pages out in. Multiply by the device pixel ratio for an estimate of the panel: 1536 x 864 CSS pixels at 1.25x is about 1920 x 1080 device pixels, a full HD panel at 125% scaling. Browser zoom changes the ratio.
- Why does my browser say Win32 on 64-bit Windows?
- MDN notes that modern browsers return Win32 on Windows even on a 64-bit version, and calls navigator.platform unreliable for detecting a browser. The page shows it as a platform string, not as the name of your operating system.
- Are the processor and memory figures exact?
- No. navigator.hardwareConcurrency counts logical processors, and MDN says a browser may report fewer. navigator.deviceMemory is rounded to a power of two and clamped between limits, works only on https pages and is missing in some browsers, so the page writes about 8 GB (rounded and capped by the browser) or Not reported by this browser.
- What do Do Not Track and Global Privacy Control mean?
- Do Not Track is a deprecated, non-standard setting that reads 1, 0 or nothing. Global Privacy Control reads On when you have said you do not consent to a site selling or sharing your personal information; MDN lists it as limited availability, so the row appears only where the browser has it.
- What is browser fingerprinting?
- MDN describes it as websites identifying a particular browser by collecting and combining its distinguishing features, such as the browser version, time zone, preferred language and display size. This page only shows you values a site could see; it does not hide or change any of them.
- Does this page send or store my browser details?
- This tool reads these values in your browser and does not send them anywhere or store them. The site itself keeps your recent tools and visit streak in this browser (localStorage).
