UUID Generator
Generate RFC 4122 version 4 UUIDs in bulk and copy them with one click, entirely in your browser.
What is a UUID v4?
A Universally Unique Identifier (UUID) is a 128-bit number written as 32 hexadecimal digits in the
form xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx. Version 4 UUIDs are generated from random data, so
each one is effectively unique — perfect for database primary keys and API identifiers.
UUIDs are generated locally in your browser using the Web Crypto API, so nothing is sent to any server.
