Keyboard Test FAQ
Short answers about testing a keyboard in your browser: what is detected, which keys a web page cannot see, privacy, other keyboard languages and testing on a phone or tablet.
Keyboard test questions
Is this keyboard test free?
Yes. Every test on keyboardtest.co is free, runs in your browser and needs no account, app or download. There are no ads and no sign-up.
Does the site record my key presses?
No. Everything happens in your browser and nothing is sent to a server or saved. Visits to the site are counted anonymously by Cloudflare Web Analytics, without cookies and without any key data.
Is this a typing speed test?
No. This site checks that the keys of your keyboard work. It does not measure how fast you type.
Which keys can a browser not detect?
Fn is usually invisible. Print Screen only sends a release on Windows. Media keys and system shortcuts such as Ctrl+Alt+Delete, Alt+Tab or Windows+L are often taken by the operating system first.
Why does the page lose my key presses?
The page only receives keys while it has focus. The Windows key, Alt+Tab and some shortcuts move focus elsewhere. Click on the page again and continue.
How do I test a keyboard with a different language?
The test uses physical key positions, so any language works. Tick UK/EU layout for keyboards with a tall Enter key and an extra key next to the left Shift. In Chrome and Edge the labels follow your layout.
Can I test a keyboard on a phone or tablet?
Yes, if you connect a physical keyboard by Bluetooth or USB. The on-screen keyboard of a phone does not report physical keys, so it cannot be tested.
Why do the left and right keys show separately?
Browsers report Shift, Ctrl, Alt and Windows or Command keys with their side, so a dead right Shift is easy to spot. Number pad keys are also reported separately from the top row numbers.
How do I leave the test with only the keyboard?
The test stops Tab from moving focus so you can test it. Press Esc and then Tab, and Tab works normally again for one press.
Keys a browser cannot always see
| Key | What happens in a browser |
|---|---|
| Fn | Usually handled inside the keyboard itself. It changes what the other keys send but is normally not reported as a key of its own. |
| Print Screen | On Windows and Linux the system takes the key press, so browsers only receive the key release. This test counts that release as a working key. |
| Windows key | Usually detected, but releasing it opens the Start menu and the page loses focus. Shortcuts such as Windows+L are handled by Windows and never reach the page. |
| Command on a Mac | Detected. Many Mac browsers do not report when other keys are released while Command is held, so this test releases them when you let go of Command. |
| Caps Lock on a Mac | Chrome and Safari report one event when Caps Lock turns on and another when it turns off, so the key stays lit while Caps Lock is on. |
| Media and volume keys | Often taken by the operating system. Some browsers report them, others do not. |
| F11, Ctrl+W, Ctrl+T, Ctrl+N, Alt+F4, Alt+Tab, Ctrl+Alt+Delete | Reserved by the browser or the operating system. The page cannot always stop them, so test these keys on their own rather than in a shortcut. |
