Keyboard Tester
Check that every key registers correctly — including letters, numbers, function keys, modifiers, and navigation keys. Useful for catching stuck keys or missing inputs.
About TestMyPC
Quick browser-based checks for your PC and devices
TestMyPC helps you quickly check common computer, browser, audio, camera, controller, keyboard, display and internet issues directly in your browser. It is built for practical first-pass troubleshooting: no installs, no accounts and no unnecessary ceremony.
What can you test?
Webcam Tester
See a live camera preview, switch between connected cameras, toggle mirror mode, and confirm stream resolution before calls or recordings.
Microphone Tester
Monitor your microphone input level in real time and select a specific audio input device. Quickly confirm your mic is working before joining a call.
Sound Tester
Run a set of audio checks including left and right channel tests, stereo balance, bass, and treble. Useful for checking speakers or headphones for issues.
Mouse and Touchpad Test
Test pointer movement, left and right click events, double-click, and scroll direction. Helpful when checking a trackpad for responsiveness or gesture issues.
Screen Display Test
Review screen size, pixel ratio, colour panels, gradients and grid sharpness for quick display inspection.
Internet Speed Test
Estimate your connection latency, download speed, and upload speed with a staged browser test. Useful for checking whether your internet is performing as expected.
Timer
Run a clean on-screen timer with pause, reset, and fullscreen support. Includes Wake Lock where available to prevent your display from sleeping mid-session.
Why use browser-based tools?
No installs required
Everything runs in your browser. There is nothing to download, install, or update. Open the tool, run the check, and you are done.
Fast and lightweight
TestMyPC is designed to load quickly and stay out of the way. Pages are lightweight and the tools start immediately without lengthy setup processes.
Private by design
Camera, microphone, and input tests run locally in your browser. Your device data is not uploaded or stored by TestMyPC.
Works on most devices
TestMyPC runs on Windows, Mac, Linux, and most modern browsers. While some tools may have browser-specific limitations, the core tests work across the majority of setups.
Our practical experience
TestMyPC is shaped by real-world device troubleshooting: laptops with intermittent keys, desktops with awkward audio routing, webcams blocked by privacy settings, controllers that only fail over Bluetooth, and peripherals that behave differently across browsers. The goal is not to pretend a website can replace a repair bench, but to give people a clear, trustworthy starting point before they spend money, reinstall drivers or contact support.
We focus on checks that are understandable and useful in everyday situations: preparing for a video call, testing a second-hand laptop, confirming whether a headset is selected, or gathering browser details for an IT support request.
Who is it for?
TestMyPC is useful for a wide range of people and situations:
- Before a video call or online meeting — confirm your camera and mic are working before joining
- Remote workers and students — quickly diagnose whether issues are with your hardware or connection
- Gamers and streamers — test audio, input response, and internet speed before a session
- Buying or selling a device — run a quick check on a second-hand laptop or PC to verify key hardware works
- Repair shops and IT support — use the tools as a fast first-pass check before deeper hardware investigation
- Home users — troubleshoot issues without needing to install additional software
Limitations
Browser-based testing has real advantages, but it is worth being aware of what these tools cannot do:
- Not all key events are detectable in every browser — some system keys (e.g. volume, media buttons) may not register
- Internet speed results are estimates and may differ from dedicated speed testing services or native app results
- Camera and microphone access depends on browser permissions — if permission is denied, the tool cannot function
- Results may vary across different browsers, operating systems, and hardware configurations
- TestMyPC cannot diagnose internal hardware faults, driver problems, or OS-level issues
For detailed hardware diagnosis, professional repair tools or OS-level utilities will always be more thorough than browser-based checks.
