Our random string generator uses the Web Crypto API's cryptographically secure random number generator, which provides the same level of security as professional password managers and security applications. This random string generator ensures the randomness is suitable for generating passwords, API keys, and other security-sensitive strings.

Absolutely safe! All string generation happens locally in your browser using JavaScript. We never send your generated strings to our servers, and we don't store any of your data. Your privacy is completely protected.

You can generate up to 1,000 strings at once, with each string up to 256 characters long. This limit ensures optimal performance while meeting most use cases. If you need more, simply run the generator multiple times.

Yes! Our generator creates cryptographically secure random strings perfect for passwords. We recommend using a mix of uppercase, lowercase, numbers, and symbols with at least 12 characters for strong passwords.

When you enter custom characters, our random string generator will only use those specific characters to create your strings. This random string generator feature is perfect for specialized use cases like generating hex codes, DNA sequences, or strings with specific symbols. You can use the quick preset buttons for common character sets or type your own.

Yes, our random string generator is completely free to use with no limitations, registration requirements, or hidden costs. We believe in providing valuable tools accessible to everyone.
