Random String Generator
Generate random strings with custom length and characters.
Online random string generator: create unique and secure texts
Random text strings have multiple applications in the digital world. From generating unique identifiers for databases, authentication tokens for APIs, verification codes, to session keys and salt values for password hashing. Our generator uses the browser's Web Crypto API (crypto.getRandomValues).
You can fully customize the generated strings by choosing exact length (1 to 256 characters), character types (uppercase, lowercase, numbers, symbols), and quantity to generate at once (up to 50).
All generation is done locally in your browser. Results are not sent to any server, ensuring your generated strings remain private.
Frequently asked questions
Are the generated strings truly random?
Yes, we use crypto.getRandomValues(), the browser's native cryptographic API that generates high-quality random numbers. It is the same method used internally by browsers to generate SSL/TLS keys, so it is suitable for production use.
Can I use these strings as passwords?
Yes, you can use them as secure passwords. For maximum security, it is recommended to enable all character types (uppercase, lowercase, numbers, and symbols) with a minimum length of 16 characters. However, for specific passwords, we recommend using our dedicated password generator.
Can the generated strings repeat?
Theoretically yes, but the probability is astronomically low. With a charset of 62 characters (uppercase + lowercase + numbers) and a length of 16, there are 62^16 possible combinations (approximately 4.7 x 10^28), making repetition practically impossible.
