What is a UUID?
A UUID (Universally Unique Identifier), also called GUID, is a 128-bit identifier guaranteed to be unique across time and space. UUID v4 uses random numbers to generate identifiers with an astronomically low probability of collision, making them ideal for database primary keys, session tokens, and distributed system IDs.
Key Features
- Generate 1 to 1000 UUID v4s at once
- Uppercase or lowercase output
- Toggle hyphens on or off
- Wrap UUIDs in curly braces {} or quotes ""
- Copy all UUIDs to clipboard or download as .txt
- Generation history with restore function
- 100% browser-based using crypto.randomUUID()
UUID v4 Format
A standard UUID v4 looks like: xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx where x is a random hexadecimal digit and 4 indicates version 4. The y digit is constrained to 8, 9, a, or b to indicate the variant.

- Set the number of UUIDs to generate (1–1000).
