Guide

How to Use This Free Online Keyboard Tester

No download, no login — works instantly in your browser. Follow these 5 simple steps.

01
Press Any Key on Your Physical Keyboard
Start typing — press any key and it instantly lights up cyan on the on-screen layout. Every key is detected including F1–F12, Shift, Ctrl, Alt, Win, arrow keys, and the full numpad. No setup needed.
02
Watch Keys Turn Green After Testing
Once you press a key, it turns green and stays highlighted — confirming it works. Dark keys are still untested. At a glance you can see exactly which keys pass and which ones may be broken or stuck.
03
Track Your Coverage with Live Stats
The stats panel shows Tested, Total, Coverage %, and Last Key — all updating in real time. The progress bar fills as you test more keys. Reach 100% to confirm every single key on your keyboard is working.
04
Pick a Sound Profile for Audio Feedback
Choose from  Mechanical, Soft, Clicky, or  Typewriter to hear a unique sound on every keypress. Prefer silence? Toggle sound OFF anytime with the Sound button above the keyboard.
05
Reset and Start a Fresh Test Anytime
Click ↺ Reset to clear all highlights and start over — useful when testing a different keyboard. You can also click any key directly on the on-screen layout with your mouse or finger (on touchscreen) to test it individually without using the physical key.
