What is a UUID (or GUID)?
A Universally Unique Identifier (UUID), also known as a Globally Unique Identifier (GUID) in the Microsoft ecosystem, is a 128-bit label used for information in computer systems. This tool generates Version 4 UUIDs, which are created using secure, cryptographic random numbers directly in your browser.
UUID Generator FAQ
Are the generated UUIDs truly random and unique?
Yes. We utilize the Web Crypto API (crypto.randomUUID()) built directly into modern browsers. This ensures highly secure, cryptographically random generation. The chance of a collision (generating the exact same UUID twice) is statistically indistinguishable from zero.
How many UUIDs can I generate at once?
You can generate up to 5,000 UUIDs per click. Because the process is handled entirely client-side on your device's CPU, the generation is instantaneous and does not require any server-side database communication.
