Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier that is practically unique. UUID v4 uses random values, making collisions extremely unlikely.
Will my generated UUIDs be uploaded?
No. All generation happens locally in your browser. Your UUIDs never leave your device, fully protecting your privacy.
What is UUID v4?
UUID v4 uses random or pseudo-random bytes for most of the identifier, providing uniqueness without a central authority. It is the most common UUID version.
Can I generate UUIDs without hyphens?
Yes. Toggle the 'Hyphens' option off to generate compact 32-character hex strings without dashes, useful for database keys.
Can I generate multiple UUIDs at once?
Yes. Set the count to generate up to 100 UUIDs at once, then copy them all with one click.
