UUID v4 Generator
Generate up to 100 RFC 4122 version 4 UUIDs at once with the browser crypto generator, then copy the list.
Good to know
- Version 4 UUIDs are random, not sequential. For sortable IDs look at UUID v7 or ULID.
Common questions
How unique are these UUIDs?
Version 4 UUIDs carry 122 random bits, so a collision is practically impossible for normal use.
Why not use sequential IDs?
v4 is random and not sortable. If you need sortable identifiers, use UUID v7 or ULID.
Can I generate more than 100 at once?
The page caps each batch at 100 to keep the tab responsive. Generate again for more.
