Free Online Utilities & Generators

These are the small in-the-moment tools — the ones you open in a new tab, use for thirty seconds, and close. They're individually simple, but together they replace half a dozen apps that would otherwise want an account and a download.

Security is the most-used corner: the Password Generator builds strong, customisable passwords (length, character classes, exclude ambiguous chars) using your browser's cryptographic randomness, and the Password Strength Checker scores any password against modern attack speeds so you can see whether it would survive a real attempt. Neither tool sends your password anywhere — they can't, because the math runs locally.

For sharing, the QR Code Generator turns a URL, text snippet, Wi-Fi credential or contact card into a scannable QR code with adjustable size, error correction and colour. For focus, the Pomodoro Timer cycles work and break intervals with browser notifications, the Stopwatch handles laps and splits, and the Online Notepad gives you a distraction-free text area that auto-saves to local storage.

Round it out with an IP Lookup tool (geolocation, ISP, ASN), a Random Picker (names, numbers, options) for fair draws, and a To-Do List that stores tasks locally — no account, no sync to a server you don't control.
