Tous les Outils de Test de Clavier
Des outils gratuits s’exécutant dans votre navigateur, sans aucune installation requise. Ils sont organisés en quatre groupes : tests selon la disposition du clavier, diagnostics matériels (chatter et ghosting), tests de touches individuelles et tests de frappe et performance.
Si vous rencontrez un dysfonctionnement, le tableau des symptômes ci-dessous est le moyen le plus rapide de trouver l’outil adapté. En cas de doute, commencez par le test de clavier principal. Observez les touches détectées avant d’approfondir.

Comment ces outils se complètent
Les dispositions facilitent la comparaison physique. Les outils de diagnostic isolent un symptôme à la fois : frappes répétées, touche bloquée ou combinaison défaillante.
Start with individual keys, then test the exact combinations you use. Compare the ghosting test with the rollover counter to distinguish missing events from an observed simultaneous-key count.
Typing and WPM tools report practice scores. Sound profiles are synthesized effects, not recordings or measurements of your keyboard. Read how we test for the measurement definitions and browser limits.
Tests pour le Gaming
Check gaming key combinations, then compare missing combinations, simultaneous key counts and browser timing intervals.
Dépannage
Follow the guides for keys not working, double typing, wrong letters, input lag or inspecting a used keyboard.
Foire aux questions
Which keyboard test should I start with?
Start with the main keyboard test on the homepage. It checks every key on a full layout in one pass, which tells you whether the problem is one key or many. Only then move to a specialised test — the symptom table on this page maps each complaint to the right tool.
Are all of these tools free?
Yes. There is no account, no install, no extension and no trial. Test calculations run locally. Keyboardtest’s diagnostic code does not upload key events. Separate analytics, advertising and optional translation are described in the privacy policy.
Do these tests work on a laptop, Mac or Chromebook?
All of them work on any device with a physical keyboard. Several are built around a specific layout — the Mac, laptop and Chromebook tests draw the real key arrangement for those machines, which matters because a generic layout mislabels keys like the Chromebook Search key.
Can a browser test find a hardware fault?
It shows whether a tested key reaches this browser in the current session. Compare other apps, browsers and connections before deciding on repair. It cannot tell you whether the cause is the switch, the ribbon cable or a remapping tool. Where that distinction matters, each tool says so on its own page.
Do you record what I type?
Keyboardtest’s diagnostic code keeps key events in page memory and does not upload them. Preferences may be saved locally. See the privacy policy for separate third-party services.
What is the difference between the typing test and the WPM test?
The typing test focuses on accuracy and shows your errors as you make them. The WPM test focuses on speed, reports net alongside raw words per minute so you can see what your errors cost, and explains how the score is calculated.
