What this site is
Key & Pixel is a collection of free utilities that run entirely in your web browser: hardware testers for keyboards, mice, screens, cameras and microphones; timers and clocks that keep accurate time; and text tools that handle unicode properly. There is no account, no install, and no upload step — the page you open is the tool.
Why we built it
We kept needing the same things — a keyboard tester that shows a real layout rather than a list of key codes, a chess clock that doesn't drift after ten minutes, a character counter that counts an emoji as one character — and kept landing on pages that were mostly adverts with a small, half-working tool in the middle. So we built the versions we wanted, and published them.
How the tools are built
- Everything is local. Keystrokes, mouse movements, camera and microphone streams, and any text you paste are processed on your device and never sent to a server. You can check this yourself in your browser's network panel.
- Each tool explains itself. Under every tool there is a plain-English guide to what it measures, how to read the result and what to do about it.
- We test against the best. Before a tool ships we compare it with the most-used alternatives and make sure ours does everything they do, then at least one thing more.
- It keeps improving. Once a month we look at what people use, what they search for and what breaks, and add or improve tools accordingly.
How the site is funded
The site is free and supported by a small number of clearly-labelled adverts, placed below the tools so they never get in the way of using them. We don't sell data — we don't have any to sell.
