Free UUID Generator
Generate unique identifiers (UUID v4 & v7) instantly.
💡 What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit unique identifier. UUID v4 is randomly generated, while UUID v7 is time-ordered and sortable by creation time. Both are used for databases, APIs, and unique keys.

❓ Frequently Asked Questions
What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit unique identifier standardized by the Open Software Foundation. It is used to uniquely identify information in computer systems, databases, and APIs.
What is the difference between UUID v4 and v7?
UUID v4 is randomly generated using random numbers, making it completely unpredictable. UUID v7 is time-ordered, combining a timestamp with random data, which makes it sortable by creation time and better for database indexing.
Is this UUID generator free?
Yes, our UUID generator is 100% free with no hidden charges. No registration or sign-up required. Generate as many UUIDs as you want.
Are generated UUIDs truly unique?
Yes, UUIDs are designed to be universally unique. The probability of generating the same UUID twice is astronomically small (1 in 2^128), making them practically unique for all real-world applications.
How many UUIDs can I generate?
You can generate an unlimited number of UUIDs. Our tool uses cryptographically strong random number generation and has no limits on usage.
