What is a Device Information?

A Device Information tool displays all the technical details your browser reveals about your device — operating system, browser version, screen resolution, viewport size, CPU cores, memory, language preferences, timezone, installed fonts, hardware capabilities, and more. This information is what every website you visit can detect about you and your device, which is useful for developers debugging responsive designs, security researchers understanding browser fingerprinting, and anyone curious about what their browser exposes.

How Does It Work?

Open the tool and it instantly displays all browser-accessible device information: (1) Navigator Info: userAgent, platform, language, cookie enabled, doNotTrack, (2) Screen: resolution, color depth, pixel ratio, available screen area, (3) Hardware: CPU cores, device memory (if available), battery status, (4) Network: connection type (4G/WiFi/Ethernet), downlink speed, (5) Media: supported video/audio codecs, WebGL renderer, (6) Storage: available quota, persistent storage status. All data is displayed, not sent anywhere — nothing leaves your browser.

Formula

Information Categories (all from browser APIs):\n\nBrowser Identity:\n• User-Agent (navigator.userAgent)\n• Browser: parsed from UA (Chrome 125, Safari 18, etc.)\n• Language: navigator.language\n• Platform: navigator.platform\n• Cookies: navigator.cookieEnabled\n\nScreen:\n• Resolution: screen.width × screen.height\n• Available: screen.availWidth × screen.availHeight (minus taskbar)\n• Pixel Ratio: window.devicePixelRatio\n• Color Depth: screen.colorDepth bits\n\nHardware:\n• CPU Cores: navigator.hardwareConcurrency\n• Memory: navigator.deviceMemory (GB, Chrome only)\n• Touch: navigator.maxTouchPoints > 0\n\nNetwork:\n• Connection: navigator.connection.effectiveType (4g/3g/2g)\n• Downlink: navigator.connection.downlink (Mbps)\n\nBattery (if available): navigator.getBattery(): level, charging\nGPU: WebGL renderer string (identifies graphics card)\n\nFingerprinting note: combining these values creates a unique device signature

Who Uses This Tool?

• Web developers testing responsive design on different screen sizes
• Support technicians getting device details from users for troubleshooting
• Privacy-conscious users checking what fingerprint information their browser leaks
• QA engineers verifying browser/platform combinations during testing
• Anyone curious about their device's technical specifications

Pro Tips

• Your browser reveals significant fingerprinting data — the combination of user agent, screen, fonts, and hardware details creates a highly unique signature
• To reduce fingerprinting: use Firefox with resistFingerprinting enabled, or Brave browser with fingerprinting protection. The trade-off: some sites may break
• Device memory (navigator.deviceMemory) is a Chrome-only API. Firefox and Safari don't expose it — which itself is a fingerprinting signal
• Screen dimensions reported by JavaScript may not match physical pixels due to devicePixelRatio. A '375×667' phone with 3× DPR has 1125×2001 physical pixels

Frequently Asked Questions about Device Information

Is my browser leaking private information?

All the information shown is accessible to every website you visit via standard browser APIs. It's not a 'leak' — it's the browser providing information needed for proper rendering. However, the combination of data points can uniquely identify your browser (fingerprinting).

Can I spoof or hide this information?

Yes, to varying degrees. Browsers offer privacy settings to limit fingerprinting. Extensions can spoof User-Agent strings. Brave and Firefox have built-in fingerprinting protection. Tor Browser standardizes these values across all users to blend in.
