About CoolTool
CoolTool is a collection of free online tools built to be fast, private, and effortless to use.
Our mission
We build small, focused tools that solve one problem well — no downloads, no sign-ups, and no tracking.
Privacy by design
Every tool runs locally in your browser. Your files, text, and data never leave your device, and we do not store or process your inputs on our servers.
