Why these run in your browser
Every tool on this site is client-side. That is a deliberate choice, and it has three practical consequences.
Your data stays on your machine. There is no upload step, no server processing and nothing stored. You can confirm this yourself: open your browser's developer tools, switch to the Network tab and use any tool. Nothing is sent.
Results are instant. There is no round trip to wait for, so the output appears as fast as the browser can compute it.
It is free. There is no server cost per request to pass on, which is why there is no paywall and no usage cap.
