About TestMyPC

Quick browser-based checks for your PC and devices

TestMyPC helps you quickly check common computer, browser, audio, camera, 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?

Keyboard Tester

Press every key and see which ones register, stick or repeat, on a Windows UK or Mac layout.

Mouse & Touchpad Test

Check pointer movement, left and right clicks, double-clicks and scrolling from a mouse or touchpad.

Typing Speed Test

Measure net words per minute and accuracy over 15 seconds to 2 minutes.

Reaction Time Test

Five rounds with false-start detection, measuring your average and best reaction in milliseconds.

Webcam Tester

See a live preview, switch cameras and confirm resolution before a call or interview.

Microphone Tester

Watch a live level meter to confirm your mic works and is loud enough, and pick the right input.

Sound Tester

Play left, right, bass and treble tones to find a dead speaker, a one-sided headset or distortion.

Screen & Dead Pixel Test

Full-screen colours, gradients and grids for spotting dead pixels, banding and backlight bleed.

Refresh Rate Test

Check your monitor is really running at 60, 120, 144 Hz or more, and how smoothly frames arrive.

CPU Benchmark

Single- and multi-core scores, a 1–90 minute throttling stress test and a public leaderboard.

GPU Benchmark

An adaptive WebGL load that finds your graphics limit, with a stress test and leaderboard.

System Info

See the screen, browser, memory and processor details your browser can detect — handy for support requests.

Internet Speed Test

Measure ping, download and upload speed, and see what the numbers mean for calls and streaming.

Used Laptop Checkup

A guided 12-step inspection for buying second-hand, with a report you can export.

Timer

A full-screen timer that keeps the display awake — for presentations, workshops and study sessions.

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 runs TestMyPC

TestMyPC builds and maintains the browser tools on this site and writes the guides that go with them. Each guide is written alongside the tool it uses and updated when browsers or operating systems change how things work.

TestMyPC is based in the United Kingdom. You can reach us through the contact page.

How the guides are written and kept up to date

Every article on the TestMyPC guides is written and maintained by the same people who build the diagnostic tools. Guides are grounded in how the tools actually behave across Windows, macOS and the major browsers, and in the troubleshooting patterns we see through reader feedback.

We hold the guides to a simple standard: be specific, be honest about what a browser can and cannot detect, and always give the reader a way to verify things themselves rather than asking them to take our word for it. When something changes — a browser permission flow, an operating-system settings path — we update the affected articles and show the updated date on each post.

Some guides include short example scenarios. These are illustrative situations that show how a test result maps to a fix; they are not testimonials or case studies of named customers.

Benchmark ratings are calibrated against the results visitors submit to our public leaderboards, and are revised as more results come in. If you find an error in any guide, report it and we will correct it.

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.
