Everything you need to know about NumberGenerator.ai
We use the Web Crypto API's getRandomValues() method, which provides cryptographically secure random numbers (CSPRNG). This is the same technology browsers use for HTTPS/TLS encryption, ensuring truly unpredictable results suitable for security-sensitive applications.
Absolutely. All number generation happens locally in your browser. Nothing is sent to our servers. We don't use tracking cookies, analytics, or collect any personal information. Your generated numbers, settings, and usage patterns remain completely private.
Our generators use cryptographically secure methods (CSPRNG), making them suitable for many applications including password generation. However, for gambling or regulated activities, always verify compliance with local regulations and use certified RNG systems as required by law.
Yes! NumberGenerator.ai is fully responsive and works on all devices - smartphones, tablets, and desktop computers. The site can also be installed as a PWA (Progressive Web App) for offline use on supported devices.
We offer embed codes for most tools. Look for the 'Embed' button on any tool page to get copy-paste HTML code. We're also working on a REST API for programmatic access (coming soon).
No account required! All tools are free to use without registration. Your favorites and recent tools are stored locally in your browser for convenience, but you can use everything anonymously.
The 'pseudo' in CSPRNG refers to how the numbers are algorithmically generated, but they are cryptographically indistinguishable from true randomness. The Web Crypto API draws from the operating system's entropy pool (which includes hardware events, thermal noise, etc.), making the output suitable for cryptographic applications.
Each tool is optimized for specific use cases: Range generators for number picking, Password generators for secure credentials, PIN generators for numeric codes, Dice/Coin for game simulation, and Lottery for number combinations. The Combo Generator lets you run multiple operations at once.
