UUID Generator
Generate random UUIDs in various formats
UUID Generator Online - Free Random UUID Tool
Generate random UUIDs (Universally Unique Identifiers) with FileMuncher's free UUID generator. Create v4 random UUIDs for database records, API identifiers, session tokens, or any application that needs unique identifiers. Generate single or bulk UUIDs instantly.
UUID generation happens entirely in your browser using the Web Crypto API for cryptographically secure random numbers. No data is sent to any server. This is important for generating identifiers that will be used in production systems, as the randomness quality is equivalent to server-side generation.
Generate UUIDs one at a time or in bulk. Copy to clipboard with one click. The standard v4 format (xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx) is used, which is compatible with all major databases and programming languages. Works on any modern browser.
