Preguntas Frecuentes
Are the strings truly random?
Yes, the strings are generated using JavaScript's Math.random() function with uniform character selection from the alphanumeric character set. Each character position is independently and randomly selected, producing unpredictable strings suitable for most general-purpose uses.
Can I include special characters?
The random string generator uses alphanumeric characters (A-Z, a-z, 0-9) by default. If you need strings with special characters and symbols, try our random password generator which offers toggles for uppercase, lowercase, numbers, and special symbols.
Is this tool free?
Yes, the random string generator is completely free to use with no registration required. There are no usage limits or hidden costs. Generate as many random strings as you need for identifiers, tokens, test data, or any other purpose.
