About the uuid generator
A UUID (universally unique identifier) is a 128-bit value written as 32 hexadecimal digits in the pattern 8-4-4-4-12. Version 4 UUIDs are almost entirely random, so two generated independently practically never collide.
Developers use them as database keys, request IDs and file names when they need uniqueness without a central counter. This tool builds them with the browser's cryptographically secure randomness.
Generate them in bulk, optionally uppercase or wrapped in braces (a common format in some ecosystems), and copy the whole batch at once.
