Random Number and String Generator

Generate random integers inside a minimum and maximum range, decimal numbers with a chosen precision, or random strings with custom length and characters. Results can be unique, sorted, and copied as one value per line.

Browser-based random generator

Random values are created locally with the browser Web Crypto API. Number mode is useful for sample data, test cases, drawings, and numeric lists. String mode can create numeric codes, mixed identifiers, and custom-character tokens without sending the generated values to a server.

Unique values and production secrets

Unique mode retries until it fills the requested count, so the selected range or character set must contain enough possible values. For passwords, API credentials, and recovery codes, generation is only one part of security: store the result in a trusted password manager or secret manager and avoid leaving sensitive values in clipboard history.
