How to check your computer specs without installing apps
See your processor, graphics, screen, battery, and other device details in your browser, then learn which specifications you need to check in system settings.
You want to know what processor, graphics, screen, or battery your computer has, but you do not want to install a system information app. Your browser can show some of these details using information your computer already makes available.
Use TooLab’s System Info to check the details your browser can read. Then use the built-in settings in Windows or macOS when you need an exact number or model.
Check your computer specs in a browser
- Open System Info in your browser. It runs on your device and does not need an installation.
- Look through the processor, graphics, and screen information. These sections show details the browser can access about your computer.
- Check the battery section if you are using a laptop, tablet, or phone. Battery details appear only when the browser reports a battery.
- Look at the network information, then note anything you want to compare with your operating system’s settings.
The browser may not report every detail, and some information can be incomplete. If you are checking a used computer, troubleshooting a game, or comparing a device with its advertised specifications, confirm important numbers in the operating system too.
What the results mean
Processor information
The processor, often called the CPU, does the general computing work. Its name and other details can help you identify the type of computer you have or compare it with the requirements for an app or game. If you need the exact processor model, check the system settings as well.
Graphics information
Graphics hardware, or the GPU, draws images and video and can help run games and creative apps. A computer may have integrated graphics built into its processor, a separate graphics card, or both. Check your operating system’s display or hardware details if the browser’s information does not make the model clear.
Screen information
The screen section reports display details that the browser can read. If you are checking the resolution or comparing connected monitors, verify the active display settings in Windows or macOS. A browser report describes what it can see, not necessarily every capability of the screen.
Battery information is missing
This does not automatically mean the battery is broken. Battery details are available only on devices whose browser reports a battery, such as many laptops, tablets, and phones. A desktop computer or a browser that does not expose battery data may show no battery information.
RAM size is not exact
RAM is the computer’s short-term working memory. Browsers receive only a rounded hint about its size, not the exact installed amount. Use your operating system’s About or system information screen if you need the precise number.
Find exact specifications in system settings
On Windows 11
Open Settings › System › About to see the device specifications, including the processor and installed RAM. For more detail, open Task Manager with Ctrl + Shift + Esc, select Performance, and choose CPU, Memory, or GPU in the list. The GPU view can help identify which graphics processor Windows is using.
To check your current screen resolution, open Settings › System › Display and look at Display resolution. If you have multiple screens, select the screen you want to check first.
On macOS
Open System Settings › General › About to see the Mac’s chip or processor and memory information. For more hardware detail, search for System Information with Spotlight and open it. Select Hardware or Graphics/Displays to inspect the details macOS provides.
To check the current screen resolution, open System Settings › Displays. If more than one display is connected, select the display you want to inspect.
Why a browser may not show every spec
A browser is designed to keep websites from freely inspecting your computer. It exposes selected information for useful features, but it does not give a web page the same access as an installed system utility. That protects your privacy and limits what a website can learn about your device.
This is why the RAM result is only a rounded hint, and why some information can vary by browser or operating system. Battery data may be unavailable, and details shown for a screen or graphics device may not include every supported feature. A missing browser result is not proof that the component is absent or faulty.
For a quick overview, use the browser test. For an exact model number or installed memory amount, confirm it in your operating system’s built-in settings.
