How do I check my PC specs online?

Visit InspectMyPC. Your CPU cores, RAM, GPU, OS, browser, screen resolution, and more are detected automatically using browser APIs. No downloads required.

What PC specs can be checked in a browser?

Browser-accessible specs include: CPU logical core count, device memory (RAM), GPU vendor and renderer via WebGL, screen resolution and pixel ratio, OS name and version, browser name and engine, battery level, network connection type, and storage quota.

Why is my RAM showing as a round number?

The navigator.deviceMemory API intentionally returns rounded values (0.25, 0.5, 1, 2, 4, 8 GB) to protect user privacy against fingerprinting. Your actual RAM may differ slightly.

How do I check my full PC specs in Windows?

Press Win+Pause/Break for basic specs, or run dxdiag for a full DirectX diagnostic report including GPU and sound card details. System Information (msinfo32) gives the most comprehensive view.

How to check your PC specs online.

Checking your PC specs used to require opening Device Manager, running dxdiag, or installing third-party tools. InspectMyPC changes that — it reads all available hardware and software information directly through browser JavaScript APIs, presenting your full device specification instantly.

What specs can a browser detect?

CPU Cores

navigator.hardwareConcurrency

Number of logical processor cores available to the browser.

Device RAM

navigator.deviceMemory

Approximate RAM in GB, rounded for privacy protection.

GPU Renderer

WebGL WEBGL_debug_renderer_info

Full GPU vendor and renderer name string.

Operating System

navigator.userAgent

OS name, version, and architecture from User Agent.

Browser

navigator.userAgent + feature detection

Browser name, version, and rendering engine.

Screen Resolution

screen.width × screen.height

Physical display resolution and device pixel ratio.

Network

navigator.connection

Effective connection type, downlink speed, and RTT.

Battery

navigator.getBattery()

Charge level and charging state (mobile/laptop).

For specs not accessible via browser APIs — such as exact storage capacity, motherboard model, CPU model name, or BIOS version — use the built-in system tools on your operating system: System Information on Windows (msinfo32), System Information on macOS, or lshw on Linux.
