About our generators tools
The Generators category collects the small but crucial utilities that you reach for several times a week: a strong random password for a new account, a QR code to put in a slide deck, a URL-safe slug for a fresh blog post, a random number for a draw or a simulation. Every generator uses the browser's cryptographically secure random source (crypto.getRandomValues), the same source modern browsers use to derive cryptographic keys — so the output is genuinely unpredictable, not a Math.random shortcut.
The Password Generator lets you tune length and character classes (uppercase, lowercase, digits, symbols) and optionally exclude lookalike characters (0/O, 1/l/I) for easier typing. The QR Code Generator produces scannable codes for any URL, contact card, Wi-Fi credential or arbitrary text and exports them as PNG (for slides and print) or SVG (for scaling and embedding). The Slug Generator converts any title into a URL-safe form: lowercase, hyphenated, ASCII-only with diacritics stripped — perfect for blog post permalinks. The Random Number Generator handles ranges, integers vs decimals, count, and duplicate-allowed rolls.
Because everything is browser-only, the generated values never leak. A password you generate here is never logged or transmitted; a QR code's payload is encoded locally; a random number is computed on your device. That makes these tools safe for high-stakes use cases like account credentials and giveaway draws.
