UUID Generator
Generate version 4 UUIDs in bulk, right in your browser. Copy them as a list or download them as a text file.
Generate bulk UUIDs, version 4
The UUID Generator on SavyTools creates version 4 universally unique identifiers in bulk, using your browser's secure random number generator. Choose how many you need, from 1 to 500, pick lowercase or uppercase, then copy the list or download it as a text file.
How to use it
Enter the number of UUIDs, choose the case, and press Generate UUIDs. Press Copy all to copy the whole list, or Download as .txt to save it. Each UUID is shown on its own line, ready to paste into a database, test data set or configuration file.
Tips
Version 4 UUIDs are random, so they are a good choice for test data and for identifiers that do not need to be ordered or guessable. Do not use them as passwords or secret tokens on their own. If you need only one identifier, set the count to 1.
Frequently asked questions
What is a UUID? A 128-bit identifier written as 32 hexadecimal digits in five groups, for example 550e8400-e29b-41d4-a716-446655440000.
What does version 4 mean? It means the UUID was generated randomly, rather than from a name, time or device address.
How many can I generate at once? Up to 500 in one list.
Are the UUIDs unique? Version 4 UUIDs are random, so duplicates are extremely unlikely, but the tool does not check them against any database.
