Frequently Asked Questions
What is a UUID / GUID generator?
A UUID (Universally Unique Identifier) generator creates 128-bit RFC 4122 compliant unique string identifiers used in databases, software architectures, distributed system keys, and API tokens.
What is the difference between UUID Version 4 and Version 1?
UUID v4 is generated using cryptographically strong pseudo-random numbers, ensuring virtually zero collision probability. UUID v1 is generated using the current epoch timestamp combined with a node MAC address/clock sequence.
Can two generated UUID v4 identifiers ever collide?
The total number of possible UUID v4 identifiers is 2^122 (approx 5.3x10^36). The mathematical probability of a collision is so infinitesimally small that UUIDs are considered globally unique for practical software engineering.
Is there any limit on how many UUIDs I can generate?
You can generate up to 500 UUIDs per batch directly in your browser instantly. You can repeat batch generations as many times as needed for free.
Are the generated UUIDs saved or logged anywhere?
No. All UUID generation algorithms run 100% locally inside your web browser engine using the Web Crypto API. No generated UUIDs or parameters are sent to or stored on remote servers.
Is this UUID generator free to use?
Yes, TinyToolzz UUID Generator is 100% free to use with no registrations, daily limits, or software downloads required.
