Frequently asked questions
Is my UUID data stored or sent to a server?
No. All UUID generation happens entirely in your browser using JavaScript. No data is sent to any server, ensuring complete privacy.
What is a UUID?
UUID (Universally Unique Identifier) is a 128-bit number used to uniquely identify information. Version 4 UUIDs are randomly generated and have extremely low collision probability.
Are these UUIDs truly unique?
V4 UUIDs are randomly generated with 122 bits of randomness. The probability of collision is so low (1 in 2^122) that they are considered unique for practical purposes.
What is the difference between UUID and GUID?
UUID and GUID are the same thing. GUID (Globally Unique Identifier) is Microsoft's term for UUID. They follow the same format and standards.
Can I generate multiple UUIDs at once?
Yes, you can generate up to 100 UUIDs at once using the bulk generation feature.
Can I use this tool offline?
Yes, once the page loads, the tool works completely offline since all generation happens in your browser.
