GeneratorsWhat you'll find here
Instant generators for the things you need made, not calculated. The Password Generator creates strong, cryptographically random passwords to your exact rules, and the Passphrase Generator builds memorable word-based alternatives. The QR Code Generator turns any URL or text into a downloadable QR code that never expires — no redirect service, no scan limits.
Need randomness? The Random Number Generator and the Random Picker Wheel settle draws, raffles and "who goes first" fairly.
Why these generators are different
Everything is generated locally in your browser. That matters most for passwords — a password created on your device and never transmitted is one that no server ever saw. It also means no watermarks on QR codes, no expiring links and no account required to download what you just made.
