Why these tools exist
Most "free online tool" sites are a thin form wrapped in twelve adverts. We built Key & Pixel because we kept needing the same handful of things — a keyboard tester that shows every key on a real layout, a chess clock that doesn't drift, a character counter that understands emoji — and kept landing on pages that did them badly.
Every tool here runs entirely in your browser. Nothing you type, click, or record leaves your device, there are no accounts, and each tool page explains what it measures and how to read the result. If something's missing, tell us — the site grows every month based on what people actually use.
