How the GUID Generator Works
A GUID (Globally Unique Identifier) or UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. Our tool generates Version 4 UUIDs, which are generated using random or pseudo-random numbers.
The probability of a duplicate UUID is extremely low, making it ideal for database keys, transaction IDs, and unique session identifiers. Our generator allows you to create bulk GUIDs with options for uppercase formatting and curly braces to suit any programming environment.
Privacy & Security Redefined
Security is our top priority. This tool uses the standard crypto.randomUUID() browser API to generate identifiers. This ensures that the randomness is cryptographically secure according to modern web standards.
Processing is 100% Client-Side: Your generated GUIDs never leave your device. They are not sent to any server, recorded in any database, or tracked in any way. This makes our tool safe for generating identifiers for sensitive production environments or local development.
